Two women have been living in a town of nine hundred people in the Oregon Coast Range for eleven years, which is the limit anywhere, and Val Sorin has begun quietly closing things down — training a replacement at the library, not renewing the lease, packing crates of notebooks nobody is allowed to see. Kyra Davan, who runs search and rescue out of the fire hall, likes it here and says not yet, as she has said the last two times. They have Sunday dinner in a booth on Route 9 and a waitress calls them girls. Val has a man out past the grange, Daniel Eddy, who makes chairs by hand and is going blind and asks her for nothing; she is always gone by dusk. Kyra has a county deputy, Charlie Walsh, and turns the light off before he kisses her.

Then a young man arrives to stay with his uncle at the end of Fenner Road. Marcus Hale is twenty, a geology student, his mother recently dead and his father in Alaska being a coward about it. Val feels his field the moment he walks into the library and it is wrong — not sick, wrong the way a word is wrong in a language you nearly speak. Driving home one night she sees him standing in the wet grass of his uncle's yard with his head tipped back, not idly but turned and settled, holding on one particular part of the dark low in the northeast.

Underneath all of it, the field of this planet is doing something. There has been a faint eleven-year rhythm since the first winter, and this time it comes early and far stronger than it has ever come. In February, on the same day, in two separate buildings, each woman feels her body begin to turn — the cycle neither of them has had since 1607, the thing they had both believed this planet had taken away for good. Each of them hides it from the other. They sit across a booth and lie, and know they are both doing it, and do it anyway, which is worse than it would have been three centuries ago, because by now each of them knows exactly what the other is capable of saying.

Val goes further. She takes a coffee cup out of the library in a paper bag, then a hair off a coat, then a bandage out of a wastebasket, and sends them to a lab in Portland under a name that is not hers. Four regulatory markers in Marcus's blood have begun to move, a fraction at a time, in a direction she first drew on another world — they are changing him by being near him. Deeper in the data she finds something she has seen in exactly one other person: an arrangement that belongs to Kyra's own family, four thousand years old. Sorren Dael went out alone on a method nobody else ever used and did not come back, and the reason he survived a crossing no one survives alone is that somebody here was waiting at the other end. Marcus is the far end of that line. He cannot do what they do, but he can hold Sethal time — which is why he can see Val's light across a dark room, and why he looks at the sky the way he does.

Marcus works most of it out himself. He goes to Kyra at the fire hall with a list — the hands, the eyes, Ray's joke about Val not aging, a photograph he found in an uncatalogued archive box of a woman pulling people out of the Vanport flood in 1948 with Kyra's exact face — and asks who Kal is. Kyra tells him everything, and he deletes the photograph in front of her without being asked.

Kyra's cycle turns on a rescue call above Hallam Lake. Val carries her off the ridge, and Charlie Walsh looks into the cab at the shape under the blanket and writes down that she was transported by a family member. That night three people lie on the floor of Kyra's front room in the dark: Marcus holding her hand, with that faint four-thousand-year-old beat still keeping time in him, and Val behind her with a palm flat on her breastbone, spending the last of the control she has been using to hold her own body shut since February. It is not a bond. It holds for one night. Toward dawn Val's hold goes and her own light comes up through all of her, bright enough to show in a dark room, and nobody ever mentions it.

Then Val gets up quietly and drives to the closed mill, where she has spent the winter building, in secret, the thing from her notebooks that Kyra has been teasing her about since McKinley: a shielded room with a timing unit in it, driving a weak field at the beat read off the eleven sheets of lattice record. She shuts the steel door and the hum of the wrong planet stops for the first time in four hundred and nineteen years, and she rides her own cycle out alone in a metal box, in her own light, having been somebody's steady end the night before. It works badly. It does not resolve; it stops, which is not the same. She comes out and four hours are gone that she cannot account for. She never tells Kyra. Of everything kept that year, it is the one thing she carries the whole way out the other side.

By June it is over and Calderveil has noticed nothing. Val offers to go to Portland and make the original print disappear and then pushes the decision across the table instead, and Kyra says leave it — it is the only picture of her anywhere doing the only thing she is proud of, and she wants there to be one. Marcus has asked Kyra something on a porch in the long light, an offer or a question or a request for time to find out whether it could be an offer, and she has not answered, and Val sits with that and does not ask, which is the hardest thing Kyra has ever watched her do. The book ends before dawn on Val's porch, with a smudge of light low in the east, and Val saying four words out loud to nobody that have been a lie for four hundred and six years and are this morning a fraction less of one.

Sethal, four thousand years into a civilization that has had time to get set in its ways. Vaelith Sorin is the daughter of an Assembly man, raised in a narrow house on the eighth terrace above the bay, and she has arrived at the university on the promontory as a first-year in Polaris House with rooms on the upper floor that she did not ask for. Kyra Davan has come in from flat country where the herds go through twice a year, is loud in a building that does not reward it, and notices on the first day which person in a noisy courtyard has said nothing.

Val's first cycle begins to turn in her first term, and the two families move on it at once. A date is set in late spring, a house is chosen, a list of a hundred and six names is described as having been kept deliberately small, and nobody asks her anything. What nobody knows is that she has already dealt with it: she has gone up an outside stair over a lamp shop on the fourth terrace into a warm room with eleven chairs in it, and when the woman behind the desk asked whether anybody was coming she said no. That is the quiet. It is ordinary and it is legal and there is no shame attached to it that anyone will admit to, and she has told nobody at all.

It comes apart through a clerk. A parade of that formality has to be lodged, and the lodging requires a declaration that the cycle in question is unresolved, and the declaration is false. By noon the other house knows; by two her father knows; by evening it has gone two hundred miles up the coast, and Val learns that everyone has found out from the particular quality of a room going quiet when she enters it. The other family withdraws. Her father comes up and walks her along the sea wall and asks exactly one question, having thought carefully about which one to ask: were you unwell.

What she does with it is run. She goes out on the cliff path at four in the morning for eleven days and then presents herself to Rhone Tellis in the equipment room in the eleventh week of a fifteen-week season and asks to join the squad, which is not done. He takes her out to the second marker to find out whether he is wasting his season, and keeps her. Kyra tells her, early and unasked, that there is a difference between hurting yourself and getting better and that they feel identical from the inside, which is the most useful thing anybody says to her all year and which she hears as an insult.

She hears it that way for about a fortnight. Then she goes off the front at the fourth meet like someone who has never been told anything by anybody, leads for two and a half miles, finishes forty-first of sixty, and costs the school the match by nine points. And Kyra crouches in front of her in the north yard with eleven people listening and tells her she is not cold, that there is a furnace in her and she keeps shovelling herself into it, and that she is a coward who has found a way to make it look like principle. Four days later, in the wet grass with the pack going past, Kyra gets out a small tin of pressed fruit and honey and makes her eat it, and neither of them says anything at all.

After that they run at six in the morning, side by side, in silence, for eighteen consecutive mornings, and become the two fastest runners the school has put on the Headland course in nine years, and still do not speak.

And then the book does the thing it has been building the whole way. Kyra's own first cycle turns eleven days before the Headland. She reads the reference in the reading room, closes it, goes to training, tells nobody — not her mother, not the boy she is bonded to, not the physician who asks her straight out afterward — and runs. It occurs to her at about the four-mile mark, going along the top with the wind at her left shoulder, that she has done a smaller and quieter version of the exact thing she crouched down in a north yard and called cowardice. She gets about ninety seconds of that. Then it takes her, and she goes down in front of two thousand people.

Forty yards up the path, running third, in the best race of her life, in front of her father, Val hears the crowd change and does not know what it means, and then notices that she can no longer hear the breathing that has been on her shoulder for a mile and a half. She looks back. She would say afterward, on the few occasions she said anything about that morning, that she had thought about it for a long time and weighed it. It was one and a half strides. She comes back down the course against sixty people and forty yards of elbows and spikes, and what Kyra understands, lying on her back at the worst moment of her life, is that this woman has spent three months working out exactly how you get another person out of sight.

Neither of them wins anything. In the winter break the Dael archive — four thousand years of one dead man's papers, sitting in a city archive where nobody could read the notation — is transferred to the university, and a first-year called Ilen Vosse is given the lowest possible place on it and is incandescent about it. Kyra takes her word back on a cold path: not a coward, the most frightened person she has ever met, which is not the same thing, and she said the wrong one in front of eleven people and has thought about it every day since.

The book ends with three first-years walking up a cold path arguing about fold notation, under a sky nobody on Sethal has ever had any reason to name, because you do not name the room you are standing in. The name belongs to a small wet world two and a half million light years away. Two of the three will learn it eventually, and will use it for four hundred and nineteen years every time they mean home.

They take a joint field placement on Thennet, a high plateau on a world with no sea, and live for two years in a prefabricated station three miles from a holding called Ossen. The plateau is home to the Vey, eleven thousand people the briefing documents describe as a closed matrilineal society resistant to contact, and who turn out to be something the briefing documents have no vocabulary for. Kyra makes friends immediately and is wrong about them twice. Marenne Vey, roughly their own age, becomes the person both of them deal with.

The work goes badly and then well. Val's survey plan does not survive contact with the plateau; Kyra, measuring fields because somebody has to, finds a small steady unsourced residual in the data that nobody can account for and that will make her name. It will also, much later, turn out to be the most important thing either of them ever measured.

The human business goes the other way. Val, who has never in her life wanted anything in public, walks three miles down to the holding carrying a part she has already worked out how to fix, and goes on walking down, and begins something with Aro Keth, who repairs pumps, comes up in the warm season from four days east, is not Vey, and wants nothing from her at all. She says nothing about it. Kyra works it out inside a week — not from detective work, but because Val comes back with her shoulders down and stops saying where she is going.

And Kyra says nothing either, for four days and then eight and then eleven, and on the eleventh night puts down what she is holding and tells Val the thing she has been carrying since they landed: that she hid her own cycle at the Vayr, that it turned eleven days before the Headland, and that she said nothing to anybody and ran. Then, with her own news sitting right there — eleven words, I've been seeing someone — the machinery seizes, and she watches it happen from inside her own body and cannot do one thing about it, and tells herself it would be cruel to set her happiness down beside Val's shame and make her look at both. It comes out weeks later over a parcel and the wrong handwriting, and Kyra runs eleven miles in the dark on a plateau where nobody should run at night, and neither of them speaks for six days.

Underneath that, Val is doing something worse. She has been taking samples from the Vey — a hair here, a swab there — without asking anybody, because she has worked out that this population is physiologically divergent and she cannot prove it any other way. She has got very good at it. On an ordinary morning in the seventeenth month, in the station porch, in daylight, with the door open and no crisis of any kind to drive her, she lifts a hair off Marenne Vey's coat collar and turns round and finds an old woman standing in the doorway watching her do it.

There is no sentence in any language that covers the physical fact of where her hand is. The holding takes four days. Val assembles the whole of her own ruin in the first night — the recall, the committee, the public version, her father — and finds she is almost relieved, because it is a shape she has survived once. The Vey do something else entirely. They cannot punish her and will not send her home; instead they pair her, which is their way of settling a thing done in secret: it is done again, in the open, with everybody watching, and after that it is finished. On the coldest night of that year she runs it, and Kyra Davan stands at the finish stone from the middle of the afternoon because she cannot think of anywhere else to be, and afterward says into her hair: you were seen, it is done, everybody saw.

The placement runs another five months and they finish the work and the holding does not close. Val is let back inside the walls within a fortnight. And when the crates go home to Sethal, in a case of field notebooks, wrapped in a sock, there is a sealed tube labeled M.V., which she took and did not give back.

They come back to a university that has decided they are a pair, and are given a room in the west range with two benches and a door that locks, which fourth-years do not get and which is a statement. The joint submission for their Account — the piece of work a Sethal career is built on — is to come out of that room.

Kyra is bonded, and has been since before Thennet, to Emrin Solveth; it has four years in it and is coming apart in the ordinary way. She spends two months arguing twice a week with an offlander called Deyn Arrol in the lower reading room, and then stops arguing, and could have stopped the whole thing at any point in the first six weeks and knew it at the time. Val, meanwhile, drinks too much of something out of the Solara cellars on a bad evening and the two of them compare notes about their own bodies for the first time in their lives, and neither of them ever forgets a word of it.

In the eleventh week Kyra finds the mark. It is low on her back, the size of a palm, a soft grayish bloom with a paler center, and it was not there four days ago. She has seen that color twice in her life and she knows what it is before she has finished turning her head: it is what a body does after a cycle resolves without ceremony. One in eleven. Mostly dermal. Two of the eleven get something they can see afterward and one of those is permanent. She had read the literature and taken eleven days over it and decided, and what nobody could have told her was what the something would look like. In the exact language of her own species it is called the mark of the quiet, because the quiet is the usual cause — and hers was not the quiet, which is worse, and which she is going to have to say out loud to people with a file. She is a bonded woman of twenty-three.

A physician sees it at a routine examination and does what a physician is required to do, which is write it down, and the bonding registry opens a review. Val sees it coming before Kyra does, and does the thing Val does. She goes down to the registry on a Secondday afternoon and withdraws from the joint submission, which takes under an hour because the form has a name and every student in the building knows it. She does not tell Kyra. Kyra finds out in a corridor from a pleasant woman on the faculty.

The argument that follows — you removed me — is the worst of their young lives, conducted across a bench in a room neither of them crosses. Val's reasoning is impeccable and is not the point. She has decided alone, for Kyra's good, without asking, which is the same shape as the tube in the sock and will be the same shape as a coffee cup in a freezer four hundred years later.

The book ends in four rooms with four tables, with Kyra answering questions about her own body for people with a file, and the thing that is on the record at the end of it is on the record for good. Nobody ever says the useful sentence out loud. Nobody ever does.

Fifteen years have gone by in which they have not spoken. Val has been running a coastal station eleven miles north of Hessen Point, where the finding on her record arrived before she did and then stopped mattering. Kyra has held the ninth chair at the observatory at Corran Vayr for five years, which she wanted from the age of twenty-three. Both of them, in the same season, take posts at Solara, and neither writes to tell the other.

They are both thirty-eight. The thaw happens on a perimeter road at half past six in the evening and takes four miles and two hours, and after that it is Sixthdays, and the two of them walk around the outside of an institute talking about work and not about anything else, and are careful, and are happy, and do not say so.

Into this comes a man. Alexander Muler is in materials, is not from anywhere in particular, and is the only person either woman has met in fifteen years who does not want anything from where she comes from. He tells each of them, early and calmly and apparently honestly, that he cannot father children. He is with Val. He is also, in another room eleven miles away, with Kyra. Each of them knows exactly what she is doing and each of them keeps it entirely to herself, and Kyra, putting a link down beside a card with a short name on it, knows perfectly well that she has just done the exact thing she spent twenty years being unable to forgive.

Around them the other plot opens. Ilen Vosse — a man they have both known since he was nineteen and nobody listened to him — stands on a platform in front of four hundred people and says a date out loud: a hull, a crew of four, one light year out and back. The first trial flight goes up from Hessen Point on an ordinary morning in weather so unremarkable it gets mentioned in every account afterward, and comes home.

And both women are pregnant. Each works it out before any test says so. Each goes and gets it confirmed. Each decides to tell the other on Fourthday. The book ends with the two of them walking off in opposite directions along a road they have walked twenty-two times, carrying the same fact at almost exactly the same distance, each entirely certain that the silence in that yard was hers alone.

It opens with Kyra in Val's flat with nine seconds and no plan, holding a card she has just taken out of a bag, reading a name she already knows. Val comes out of the shower. By the end of the afternoon they have established that between them they have had the whole of one man's name in two rooms for a year, that he told each of them the same thing about children, and that both of them are carrying one.

The obvious explanation — that he lied — holds for exactly one night. Then they go looking for him, and he is not there. Not hiding: absent. A paternal baseline is a routine form attached to every person born on Sethal, and when the form goes out there is nothing at the other end of it. It takes eleven days to establish that nobody has done anything wrong and that Alexander Muler is a perfect hole in a planet's worth of records, and that is the part neither of them ever gets past. Somebody got to him before they did, told him what he was, and he repeated it in good faith.

Meanwhile the first crewed fold has come back four minutes and eleven seconds late against a plan of three minutes fifty-six, and nobody except Ilen Vosse thinks that is a scandal. Kyra, given the instrument records, finds the thing underneath it: during those fifteen seconds the ship's three star trackers returned three different skies. Two of them are explicable. The third is a sky that is not in the catalogue at all. Distance, it turns out, is not the variable.

The two threads join under a byre at Ossen, where Kyra goes back to the plateau and finds that the thing she measured as a student at twenty-four is an object, buried, four thousand years old, and that it is marked as his — Sorren Dael's, the man everybody at every dinner party of her life has asked whether she is related to.

Gennive Sorin and Kalenne Davan are born a fortnight apart, and nobody uses either name for longer than eleven days. And standing over a basket, two women who have never in twenty years been able to make a single decision together make one in under a minute, certain that they are being kind, and the girls will be eighteen before they find out what was decided for them.

This is the book where the science becomes a programme and the programme becomes a thing with a body count waiting at the end of it, and nobody in it does anything wrong.

The object under the byre gives them a date, and the date gives them a filing system. Sorren Dael kept his own year-count in elevens, which four generations of scholars treated as an eccentricity and converted away; converted back, his archive stops being beautiful and starts being instructions. There are eleven series in it. The first ten are how to move a man. The eleventh is how to keep him. And Dael, who is the only person in four thousand years who ever needed that step, took it out of the published method, and then got into a ship, and did not come back.

Val's group has had the return-hull work from the beginning, and finds what everybody had already looked at and not seen: the four people who flew the first fold have moved. Not damage — drift. Four regulatory markers in four ordinary men and women have shifted a fraction in the direction of a state that eleven thousand people on a plateau are simply born in. Jalen Renn, who has never been within four hours of Thennet in his life, spent fifteen seconds somewhere and came out a small distance closer to being Vey.

The drive faculty's position is not cowardice, which is what makes it hard. Four people flew, four people are fine, nothing has broken, and there is nothing to report. Ilen Vosse will not have it buried. They put it to Renn himself with the four lines about him on the table and no softening, and he agrees to let it go up. The committee receives it. The programme gets a building.

Marenne Vey comes down off the plateau for the first time in living memory, and the institute handles her badly, and what she brings is four thousand years of her people's one sentence — the thing said at a ceremony that nobody outside has ever bothered to listen to. Val has been carrying it for three years without saying it to anybody, which she is aware is the single most characteristic thing about her, and says it at last on a wall on a Fourthday: you do not cross alone.

And at the end, from her own plateau data and eleven of Ilen's modern stations, Kyra puts an arc on the residual and finds its direction, and the source is not in this system and is not close to it. It had been in the data the whole time. A hundred years of it, and Dael's forty before that, and not one person had ever had a reason to look.

Eleven years pass in which nothing happens, which is not true. The programme acquires a hierarchy and then a second one on top of it, a hall, a budget, four hundred people and then eleven hundred, and a vessel in design that will not be grown until the daughters are nearly forty.

Then Genie Sorin and Kal Davan go up to Corran Vayr, into the same cold house, onto the same squad, eleven weeks apart in nothing — and the book is largely theirs. Genie is loud and brave and hides it badly and has her mother's face. Kal says nothing she has not finished thinking, and watches, and carries things. Each of them has spent eighteen years being managed by a mother who is wrong in a different direction: Val tells her daughter nothing and calls it protection; Kyra tells her daughter everything twice a year, warmly, and calls it openness, and both girls are starving.

Their first cycles come in the tenth month, months out and unmistakable, and neither says a word about it to anybody. Genie runs with the men's squad, becomes briefly the most famous first-year in the place, and gets a register entry out of it that her mother reads without making the connection. A perfectly decent boy proposes to each of them in the same courtyard in almost the same words, and is turned down twice.

And then a sheet of paper puts it on a table. The two girls come down to Aventhal on the same coach and sit in Kyra's front room and make Val wait, and when she comes in with her coat still on and says right, her daughter asks her — once, just this once — not to do that. Val sits down at her own table in somebody else's house and puts her hands flat on it and says: ask me. They ask for three hours. It comes out in the wrong order, with Kyra crying from the fourth minute and going on answering anyway, and at the end of it the girls know who their father was and what he was not, and what was decided over a basket, and how long it has been kept.

Afterward, on the nineteenth of the fifth month, they go up the outside stair over the lamp shop on the fourth terrace into the room with eleven chairs in it. They have been speaking again for six days; it is not mended, and neither pretends it is, and there is a date. Genie stops halfway up and says she is going to be sick and Kal tells her she is not, and that she will go up eleven more steps and be extremely funny at a woman behind a desk, and that she herself will be four feet away being silent, because that is what she does.

Val Sorin, who went up that same stair alone and told the woman behind the desk that nobody was coming, stands at the bottom of it and watches her daughter go up with somebody.

The programme stops being an argument and becomes a schedule, which everybody treats as a victory and which Val knows to be a different kind of trouble: arguments can be won, and schedules only run out.

The remaining obstacle to deep-range flight is people. The interval can be held for as long as the geometry requires, and bodies cannot — not alone. Dael's eleventh series says what the Vey have been saying for four thousand years, and the programme's answer is pairs. Two enter. Resonance is not fondness; it is a measurement made with a bench and a cuff in eleven minutes, and the matching problem turns out to be hard in ways nobody predicted. Val sits on the committee that establishes all of this and writes the four lines of warning that go onto the volunteer form, and six hundred and nine people sign it, and eleven withdraw after reading her lines.

Both daughters volunteer. Genie does it in a hall, out loud, in front of five hundred people with her mother sitting second from the left at the panel table. Kal does it quietly, from a records post she took for reasons she gave nobody, and her mother finds out in a corridor from a man carrying a box who assumed she already knew. Each mother handles it in exactly the way the previous six books have been promising she would, and each of them makes it worse, and neither tells the other.

The flights get longer by degrees: short folds, four minutes, eleven minutes, thirty seconds held with two people aboard, four hours, two pairs, provisioning, food. The most remarkable thing anybody has ever done becomes a rota. The year after the thirty seconds is the worst year the programme has, and nothing breaks and nobody dies, and Kyra keeps the private list in the back of a notebook because somebody ought to and nobody asked her to: nothing failed. We simply found out what it costs, and it is not the thing we were frightened of.

The hull comes out of the tank on eleven suspension points, pale and streaming and not a shape yet, and is given a skin and a name. Kyra meets a verification officer called Ramel Aden, assembles him and labels him and files him, and passes it on. The residual climbs toward another of its eleven-year peaks and four people notice. And in a room with four windows, eleven people approve the mission in about nine minutes, and the two of them drink to it in a flat above a street of small shops on an ordinary evening with nothing at all wrong.

Five years after a committee said yes in nine minutes, the thing is a date on a wall. Nineteen people have done their hours. And then two of the crew come off the list — and the two reserves who go on in their place are Val Sorin and Kyra Davan, who are seventy-seven years old, who have spent their whole professional lives on the ground, and who have eleven days to pack.

Kyra's last morning on Sethal is spent being annoyed about a coat, which she leaves on the hook where it has hung for eleven years. At the table that morning her daughter starts a sentence — Mother, before you go, I wanted to — and Kyra talks over it, cheerfully, without noticing, because there will be a thousand more mornings. Sven Ginhov, who has had ten years of Val and no standing anywhere on any form, comes on the last evening and does not stay, and what he says is that he has written down the watering.

The outbound fold works. The nine weeks of fieldwork at a cold body a long way out from an unnamed star are the best of Kyra's professional life, and are also where she finds, at the end of a long afternoon while looking for something else, that the drift term is up. The return report is never written.

Val, meanwhile, begins something in the sixth week with Ramel Aden, the verification officer, in a stores bay on a rota that leaves four hours empty every ninth day. It is careful and it lasts the season and the most consequential two hours of it are a night when he brings work with him, the pre-fold anomaly log, and she lies on her side above him with a lamp off and watches a man read four hundred pages of dust and temperature and sign them.

The return solution is filed two days out and it is correct. That has to be said plainly, because everything afterward depends on it: computed twice from two independent starting sets, matching a solution filed at home eleven weeks earlier. Nothing is wrong. Nobody is careless. And in the fold, twenty-two seconds happen that there is no account of and never will be, because the only people who came through them were inside them.

Eleven die in the fold. Four sections come through, joined, spinning, one of them open to vacuum and sealed off by a commander closing a hatch on a room she cannot see into. They have eleven days of air by two separate calculations and Mera Tolven halves it, because she would rather come down with margin than with arithmetic. There is one habitable world within reach and it has nothing to do with anywhere they can name. The section is not a lander and will not survive an entry, so it will not make one: it will be shed in pieces, in an order worked out with the last of the power, so that what is left at the end is the two rooms with the best hull.

Six more die in the fall. Two walk out of the snow.

And at home, in parallel, their daughters wait — Genie breaking out and indexing a clean season of field data on the ninth day because she said she would, Kal following every hour of a nine-week endpoint search from a records room because the paper comes through her. It is Kal who stops at the eleventh hour on a page she has read three times already: the pre-fold anomaly review, ninety-one entries, every one checked and signed, and at the foot of it the countersignature of a verification officer. Genie is sick afterward in the street with her sister holding her coat. The book ends with the two of them at Kyra's table, with the coat still on the hook, and a thread of smoke going up out of a valley on the far side of the universe.

The first Earth book covers one year and almost nothing happens in it, which is the point.

They come down the mountain in spring with a wrecked leg between them and find a thread of smoke that does not behave like smoke from a fire, because it is a charcoal burner's mound, and below that a village called Dymná whose language neither of them can pronounce. They have a hull lying on its side on a high slope, a hut on the summer pasture, a tarn a quarter of an hour above the ship, and no idea whatever what year it is or what planet they are standing on.

The year is spent learning how to stay alive: salt, wood, root, the seventh day, a storehouse man who points at things, an Englishman called Frederick who turns up and gives them a language. Val's leg is mended over months of sessions on the floor of the second section with the light down — Kyra's hands on the shin and the other hand flat on the hull, the ship giving back what it can, in the dark, every time. Kyra works out the sky from scratch in the first clear nights: the fixed point in the north, the washed band from horizon to horizon, and at last the faint tilted smudge low in one quarter that she identifies and then laughs about with her hand over her own mouth, because the people here have already named it after a chained woman.

Kyra has a man in the village, Ondrej, for a short time and cannot put his name down for eleven days. And in the winter the change comes, and it comes for her first and it comes at night: their bodies, built for one field, going looking for a way to live in another, hour after hour between the middle of the night and the gray. Val provisioned for cold and food. What the winter actually is, is watching a woman come apart in a way neither of them has a word for and then put herself back together by morning.

The only work available is a notebook. Val cannot write, so she recites and Kyra holds it, night after night, everything either of them knows — and in among it, in that hut, in that winter, Val tells Kyra about the quiet. Kyra is the second person she has ever told. The light comes up under Val's wrists where it should not be visible at all, and Kyra sees it, because she has spent six months learning where to look.

The book ends with two women in a hut on a mountain in a country whose name they still cannot pronounce, holding on to each other in the dark while the snow starts again, and the charcoal man's hill going on breathing out its one thin thread of smoke as though nothing on the mountain had changed at all.

They come off the mountain and walk, and keep walking for the better part of a century. It takes them six years to go four hundred miles. They learn how long the questions take to assemble — a fortnight in a hamlet, a season in a town, years in a city — and they learn, over and over, how to leave.

On a valley road in bad rain in about 1620, four years in, with a long way still in front of them, Val asks how much further today and Kyra says not far now. It is two miles and there is a barn at the end of it and neither of them ever thinks about that afternoon again. It is the most important sentence in the series and it is thrown away on the page where it is born.

The Sunday dinners begin because of an administrative failure, which Kyra thinks is the funniest thing that has ever happened to her and is still saying out loud four hundred years later. They have them in inns and at fires and once, in a bad winter, in a bed with the bowls on the covers, and it counts.

They settle at last in Trieste and stay twenty-five years, which is far too long, and they both know it, and they choose it for the worst reason available, which is money, and Kyra says so out loud on the first afternoon so that neither of them can pretend otherwise later. Val has four months with a Venetian off the boat called Domenico, seventy-three years after the landing, and Kyra — who has been waiting all that time for it to happen again — enjoys every minute of it. Kyra has twenty-five years with Jakob Peršin, long enough that there is a chair in the house that is his.

And it ends the way the rules exist to prevent. Their marks stop changing; the town has had too long to look. A finding is made, Val is taken, and she spends eleven days understanding a machine, and the understanding is the only thing she has and she uses all of it. Somebody opens a door on the fourth night and does not give his name. They go out on a boat with the men at the sweeps and watch a town turn into four or five lights and then into nothing.

Four days later, in a room over a rope-walk at Capodistria, Val makes Kyra take her shirt off, and they stand there until it is properly dark.

Then, on the deck of a Dutch ship in the middle of an ocean with four thousand miles in front of them and nothing at all to walk to, with no question in front of it and nobody having asked how much further, Val says it to the water, in English. Kyra turns her head. It takes about a second. Eighty-two years and six languages they have spent looking for a word for this, and the most precise woman alive has just chosen, deliberately, to say the least accurate sentence available. Kyra says it back. Val nods once at the water. That is the whole of it, and neither of them ever discusses it again — not on that crossing, not in Boston, not in Missouri, and not in a booth on Route 9 four hundred years later.

They come up through the Narrows on a hot gray morning and go down through the town in the dusk talking at speed in the only language either of them has ever had that was theirs. They become printers, which is the trade they keep for the rest of their time on that coast, and which is a mistake Val names precisely and too late: a press is not an invisible place. It is the place where the town says what it thinks, and there is a name at the foot of every sheet.

The century is spent moving — New York, Germantown, Philadelphia, Boston — and working, and in among it Val has her Earth men, each of them handed to Kyra at the table in the flat voice before anything has happened: Matthias the papermaker, who asks her to come and live at the mill and is told no; the man in the seventh year who lasts four months and goes to Hartford, whose name Val has never said aloud since.

The astronomy runs underneath all of it. Val keeps a running account of what this planet has worked out, and watches a comet come back on the day a dead man said it would, and reads four pages out of Cambridge that explain that the only way to find out how far away anything is, is to be seen from two places at once.

Boston is Val's, and she says so at the time and goes on saying it for a century, and never lets anybody else carry any part of it. Soldiers come into the shop. The town shuts. The siege closes the passes in the third week of July and they are on opposite sides of it, and the last thing Val does on the ferry stairs with a sergeant six feet away is set up the only system they will have for eleven months — paper, and the weather, and how much you are being paid, and nothing else, and no true sentence for as long as it takes, which is how they will know each other is alive. And then, in the logistics voice, with her hands at her sides, she says four words to her.

They get eleven months of that. The first thing Val says to her afterward, in the street, in the wet, is not recorded as anything but the beginning of the rest of it.

And then, on a Tuesday in the second week of November 1795, in a room over a saddler's, with nothing whatever remarkable about any part of the day, Val says the name — in English, first, out loud. Kyra, a hundred and seventy-odd years into waiting for it, says it back to nothing at all, and a woman who is two hundred and sixty-five years old and four hundred years of light from home and has exactly nowhere to be says it again.

What changes after that is not large and does not happen all at once and Val cannot describe any of it for about four years. She says things. Not many and not loudly and not in front of anybody. And she makes, at a table in a village in a first winter and never once explains, the rule about dusk.

The last stretch is Lowell, four thousand people and a canal and no history whatsoever, and a mill girl called Lucy Bonney who goes up the Mammoth Road at twenty-two with a box and forty dollars, and about whom Kyra Davan never finds out one single thing. Val decides at the second hour of an afternoon, standing at a case setting a notice about a lost dog, that they are going to a different ocean. Kyra asks how much further. Val, with a bearing and no distance and a distance to the wrong star, shifts the box under her arm and answers.

They land on a wet rock ledge at the foot of a bluff with four hundred other people's property stacked under canvas, and winter in Westport while gold does what gold does to a town, and buy four yoke and a wagon and go out with the second company, because the first company is always fools.

The road is the middle of the book and it is a town that takes itself apart every morning and builds itself again every night. There is cholera on the river, and the first grave is not theirs, and Kyra stands in the sun looking at two halves of a ledger and cannot get past the arithmetic of it. There is a week in July when Val has to choose. There is Fort Laramie. There is a Native woman who travels with the company as far as the Green, whom the company calls Maud and the post called Madeleine and whose own name the book never gives, because neither of those is it and there is no version of it that is — and who, watching Kyra work across thirty feet of rain, is the first person in two hundred and forty-three years who could tell, and the only person on that river who would understand exactly why they would rather she did not.

And there is Independence Rock, a whale lying in the sage covered in other people's names, where two women who can never write theirs on anything look at a mountain full of marks. On the Sweetwater on the fourteenth of August 1850 they put the only permanent marks either of them will ever carry on each other: a plain closed band, inked low where nothing shows, each made by the other's hand.

They come down the Barlow Road in the last week of October with the rain starting, and the company stops being a thing in the world over the course of about four hours, and they go in the following April with two horses and a mule and nine days of food and take ground nobody wants on a lake in the Nehalem country. The first house is twelve by fourteen and they live in it for three years and Val is fonder of it than of anything she has owned since Trieste.

Then the quiet decades: neighbors, the war arriving late and sideways and already half spent, Asa Pruitt the farrier and Elias Mott the millwright, three weeks apart in sixty-one, and the end of both. The railroad meets in Utah in sixty-nine and Kyra reads it out at the table, and what it means is that the world has just become a place you can cross.

So they go back. Across a continent and an ocean and most of a third continent to a valley under a mountain that now has a hotel in it and two coaches a day and a man who hires himself out with a rope. They go up past the tarn and the rotten snow to a hut on a high pasture where the smoke is still going up, and up again to the slope above it, and the ship is still there, and it gives them something and keeps the rest.

And at the end of it there is a name in a paper. The road comes through in eighty-nine, and what Val says is: and then we go and read the paper.

They come into a city with the Willamette standing in the streets, on the back of a dray, along a plank walk on trestles put up in ten days by men who had done it before, and they stay for half a century. This is the book about paper: the census taker on the step every ten years with a new column on his schedule, the enumeration that asks your age and then your month and year of birth, and then where you were living five years ago, and a city that is slowly building the apparatus that will eventually make two women like them impossible.

It is also the book in which they finally talk. In a rented house on the east side with a bad stove, with the cold coming up from underneath, Val gives the account — truly, in order, with the numbers in it, for the first time in four hundred years. Every man she has had, and what he measured, and what it meant and did not mean. Kyra gives hers back. Later, in the second week of August in the summer of nineteen hundred, with plums going in a kitchen too hot for it and a tin on the table, the figure comes up again and Kyra laughs until she has to put it down. They burn the notes afterward. Kyra's twenty-nine entries — the eleven-year peaks, kept in the back of a notebook because somebody ought to — stay.

They set a day aside for the other thing, which they have not done for anything in four hundred years, and it is awkward from the moment they wake up, and at the end of it there is no minute and no posture and nothing that has to happen in any order at all, and nobody counts anything.

Around that: Jo Selby's stationer's on Union Avenue, where the mail for four streets is held; a boarder arrangement that becomes a landlady arrangement that becomes, on Hawthorne, sisters, which Kyra wanted and Val gave her; the Trail at the fair and the artificial mothers; the fever hospital in the autumn of 1918 with a hundred beds in the auditorium, after which Val says on a public street that she already has the city and has had it since the fourth of November and is not going to say so; the lights going in, a wire along the picture rail and a fixture in every ceiling, in the same month Val reads four pages from Cambridge about measuring distance by being seen from two places at once.

The men they have get shorter, which is to say the relationships do, and Val lays them out in a row in about six minutes and nearly takes the top of Kyra's head off, and says the sentence that settles it: there is no ledger, nobody is ahead.

And the anniversary begins, in a bedroom with the blind down and the light coming round the edges of it in two bars, and is kept every August from then on: each of them trims the other back far enough to expose the mark, by razor, three weeks to grow back.

And it ends on Memorial Day 1948, with a notice going round the flats on a half-sheet of paper, and a city of eighteen thousand people out on the floodplain between the river and the slough that is there in the afternoon and gone by dark. A hundred beds go back into the auditorium. A photographer stands on the dike. Neither of them ever knows what he got.

The last Earth book runs sixty-six years and is mostly about paper, bureaucracy, and the slow closing of a planet — Social Security numbers, references, a state that has started to think about this, offices on fourth floors with men who have been doing the work for nineteen years and like it. Every decade it gets a little harder to be two women who do not age, and they are very good at it, and they both know exactly where the end of it is.

In the middle of the book the grip is finally explained, once, and never again. It is four hundred years old and dates from the road out of Maribor. It is voluntary to send and impossible to falsify. It carries yes, no, size, age, and whether a thing is moving, and it has never managed a noun, which is why the other conversation still has to happen out loud. It cannot say less: the lightest thing available is the strongest thing available. After that single chapter it runs underneath every scene in the book and is never glossed again.

Two other things happen. In 1976 Val spends nine months of paperwork to get back onto the mountain, and what she goes up for is a line that would tell her something about her own daughter and about Kyra's, and what she gets is fifteen seconds and a dead man's locker: a comb, and a square of cloth with another woman's name stitched in it. Ramel Aden's. And in 1974 the year comes round that the arithmetic says their daughters should not outlive, and nothing arrives, and nobody tells them anything, and the notebook goes back on the shelf with a number on the page and nothing beside it, where it sits untouched for eleven years.

Against all of that, the sixty years are the best either of them has. There are two women called Anna and Ada and then two called Nora and Elsie and then nobody at all; there are four miles of highway south of Oregon City in a line of cars that has not moved in nine minutes; there is a seed catalogue nobody is reading at four in the afternoon and five hours of being entirely normal afterward. The endearments arrive in the fifties and Kyra goes slightly stupid about them every time. The marks are trimmed every August. They lace, softly, the way they do.

And at the end Val works on the way home for five years and the answer, when it comes, is not a method at all. It is a hole — the ship's own fault, and a minor Earth paper about recovering an input from a known fault, and no new hardware anywhere.

The book closes on a shelf of basalt above Hallam Lake in the rain, which they have stood on in every decade since 1851. Kyra asks how much further. It is eleven feet; she is asking nothing; it is the oldest joke in the catalogue. Val answers. Then they load a truck and go eleven miles up the road to a town of nine hundred people with a mill that closed before it had a stoplight, where nobody has ever heard of either of them.

It begins on a sofa in Oregon with a television neither of them is watching and a list on the floor with nine things on it and four crossed out. Val has four cartons from a records office in Sacramento and two from a diocesan office in Santa Fe and a county index she is not strictly entitled to, and she is looking for a line of descent with no name attached to it. On a wet Thursday in November the chain completes. It is six written words, and the reader never sees them.

She tells Kyra at twenty-five to twelve at night, badly, flatly, in a voice that gets away from her twice in six words, to a woman crouching in a wet coat on a kitchen floor. Then neither of them does anything about it for three days, which is not avoidance.

The winter is spent checking. By January the table has stopped being a table: four sheets that became nine that became a stack kept square with the edge, read and read again, because a thing half checked is a thing not checked. And in among the geometry Val finds one more thing that there is nobody to tell and no document to put it in, which is that Ramel Aden had moved, because verification does not pair.

At the end of February, in Ray Hale's yard, with a trailer up on a jack, they say goodbye to Marcus Hale. Kyra tries four openings on the road out and discards all of them, and Val lets her do it and says nothing whatever, which you can only do for somebody if you have four centuries of credit. Afterward Kyra says you didn't help me, and Val says no, and Kyra says thank you.

Then the Carpathians, and a winter in rooms above a shuttered shop in the valley, waiting for a road. Then six months of being two women with nothing at all to do in a country where they have no business, because the geometry was finished in March and the moment was not, and the moment is not a thing either of them can hurry. They go back up in the second week of September. Kyra says I've got you. There is no account of the next fifteen seconds and there never will be.

What they come out into is a field six miles inland of Aventhal, in the middle of the afternoon, at the back of the growing season. Val goes down on her hands in the dirt, because the whole of her is telling her at once that the ground is right, and there is no preparing for that.

And then the sum comes out wrong, and this is the thing the entire series has been standing on without saying so. Sethal time runs slower than Earth time. She does the sum four times, by four different roads, because she wants all four to arrive in the same place, and they do: eighty-one years on this world, four hundred and nineteen on the other one. Their father, their colleagues, their daughters — everyone they have spent four centuries burying in their own heads — are alive. Vaedom Sorin is still in the house above the water and has therefore never moved. Genie and Kal are a hundred and twenty years old. Val and Kyra are four hundred and ninety-seven, ninety-one years past the oldest age anybody on that planet has ever reached, and nobody there can see it.

The reunion is not a scene of weeping, and that is deliberate. For three days in Kal's house, neither daughter asks. Val watches the not-asking coming at her from the direction she has spent four hundred and twenty years aiming it in the other direction, and finds she has no defense prepared. What she has instead is the Sethal. The wall comes down in a long room in daylight with the door standing open onto the yard and Genie and Kal both there: the instrument goes down twice, and the three words are said out loud and allowed to stand. Two women of a hundred and twenty stand by a table and watch their mothers and never mention it again in the fifty years that follow.

The rest of the book is the seventeen households. Val makes the list on the fourth day and it takes her nine minutes, and the two of them go to the families of the seventeen who died — Aden's, which she leaves until the eleventh; Rask's, four hours inland on a holding his wife's family has worked for nine generations; the Vennars, who are the sixteenth and the one that goes well, after which Val cannot speak for about a mile; and then the seventeenth. In between, in a lane in the evening with fourteen doors still to do, Kyra laughs at something and lets it go, which she would not have done at two hundred.

They end up in a house four miles from Kal's that has been empty two years and has a bad roof on the north side, which Val knew about before she took it and took it anyway, which Kyra considers the most revealing thing the woman has done since they landed. It has a door at the end of the long room that gives onto a yard with nothing in it, and that door stands open from the fourth month to the ninth, and neither of them has ever once said anything about why. Nobody asks them whether they are staying — not Vaedom, who would think it rude, not Genie, who cannot get it out, not Kal, who worked out the whole shape of it in a fortnight and decided it was not hers, and not the two of them. There is nothing to decide yet, and both of them know what it looks like when there is.

The coda is a Fourthday walk that Kyra wants and gives no reason for, and Val, who worked out the reason somewhere around the second turning and said nothing about it, carries the bag. They sit on a headland above the only water of its kind on two worlds. Kyra puts her hand out, palm up, on the grass. Kyra asks how much further — with no road under them, nowhere beyond this, and nothing whatever left to reach.

And Val does not laugh, and does not correct her, and gives the answer she has been giving since a road out of Maribor, and this time it is true.
