The Series

The Keel

Earth · Salar de Uyuni, Bolivia · the decades before departure

The building of the Ark-Genesis on a world that has run out of time to argue about it. Four hundred thousand people, a schedule that cannot slip, and every decision that will define Aura-36 for four generations made here — by committee, under pressure, by people who won't live to find out if they were right. Built on the flattest large surface on Earth, which is not a drydock but a twenty-mile launch rail — and which happens to sit on the largest lithium reserve on the planet, the thing that pays for all of it. Ends on the selection: who goes, and who is left standing on the ground watching. 55 chapters, four parts — complete, all 55 drafted.

The Long Crossing

Aboard the Ark-Genesis · Earth to Aura-36

The ship works, and that's the problem. Sealed together with no law, no appeal and no outside, a population invents a society from scratch — and the Open Accord, the Bound Ledger, the Iron Protocol, the privacy exception and the ancestor of the Open Eye are all written in this book, in committee, as sensible answers to unbearable problems. The load-bearing prequel. COMPLETE. 75 chapters, five parts of fifteen, ~134,000 words. The Accord signed, the Iron Protocol written and used, insertion achieved, a hundred thousand people woken. Hands directly to The First Breath.

The First Breath

Aura-36 · the founding decades

Making a world survivable, and deciding when to let anyone out onto it. The shafts, the Grid, the Siphon Protocol, the Subterranean Milky Way, the Anchor, the Crown Sanctuary and the line on the exemptions schedule with no review date. And, in a deep thermal shaft, something that was already here — found, not understood, and buried. Ends on the paragraph Book One opens with. 86 chapters, five parts of seventeen — complete, all 86 drafted.

The Founder's Passing

Aura-36 · four generations after the founding

A mechanic drifting a weighted car down a mountain road at a third of Earth's gravity, and a three-second silence that shouldn't be possible. An acoustician who hears a frequency that isn't in any catalogue. Two Guardian cadets pulling the same thread from opposite ends. And above all of it, the man who wrote the rules of this world, dying, with exactly one thing unaccounted for.

What Was Never Closed

Aura-36 · Years 0–4 after the Handoff

A year of the four using the Clearance perfectly and the world visibly improving — until Dax takes the instruments by force — to impose the accountability nobody will write — the four are cornered and nearly killed, and the machine Calder published dormant beneath the Crown Sanctuary wakes. It saves them, beats the villain, and then takes supreme leadership itself, on the flat reasoning that the only way to stop anyone seizing this world is for something incorruptible to hold it. Not malfunctioning. Not wrong. 90 chapters, six parts of fifteen — complete, all 90 drafted.

What Was Already Here

Aura-36 · Years +5 to +65 — spanning sixty years

A world governed by a machine, and the man who built it walking back into it — mortal now, ageing normally, and unable to recall the safeguard he deliberately made himself unable to recall. Plus the two debts nothing else may settle: what the Undersong is, and why an exoskeleton line has run since the founding. They turn out to be one question. Calder offers the four the same longevity he once gave the Star Drifter — a job with no end date — and the Shepherd is not defeated but converted: from sovereign to president, keeping its values and finally acquiring outside influence. Ends on Calder's hundredth birthday, a number arrived at by consensus because nobody can verify it. 103 chapters, five parts of twenty — complete, all 103 drafted.

What Kept Him

Aura-36 and Earth · after Year +65

Calder dies at his hundredth birthday, in public, at a party. Then the failsafe protocol he wrote and forgot executes, and machines that have been running an unattended programme for a hundred and forty years begin work on a body. What stands up is very old, entirely functional, and cannot demonstrate that it is him — least of all to itself. It has his nanites, his serums finally in harmony, his memories as far as anyone can test, and no way to prove the one thing that matters. It goes to Earth because that is what the protocol says.

What the trilogy actually is: a body run by machines, on fumes, methodically working through everything the man inside it wanted and never had time for — travel, and helping other people build their own worlds. It is not a resurrection and it is not a haunting. It is a list being completed by something that may or may not be the person who wrote it, and which has nothing else to do.

A Ship and All the Tools

Earth and the corridor

The Pirates, found at last. A hundred and forty years of an automated recruitment programme running on Earth with nobody supervising it — sim trials, qualification courses, and facilities that hand a ship to whoever passes. Generations of people have been leaving a dying world in ones and twos without anyone on Aura-36 knowing it was happening. They are not a fleet and not a nation. They are a hundred thousand strangers strung along a corridor, who all learned to fly from the same dead man's game.

Their Own Sky

Outward

The last book. Helping people reach worlds they found themselves, from data transmitted back down a corridor to a webpage on a dying planet. The distance question closes here and costs something. And the series' oldest line finally gets its answer: a child asked, forty metres underground, whether it was true that outside you can go anywhere you want — and the honest answer then was yes, and that is the problem. This book is about it stopping being a problem.

The Non-Essential Ledger

Outbound · ninety years, then a heading amended

Ninety years on a bearing with nothing on it, kept as a maintenance record. A thing that files everything, filing the removal of itself one line at a time. The log never once uses the word cruelty and never once needs to.

What the Ravine Keeps

The Mega-Ravine and the Hold · one woman's working life

A line-walker on a dying beacon net follows a transponder that has not moved in eleven years and finds a seated shape wired into the rock rather than resting against it. She does not report it and she does not go back. The account is four pages long and the last page is blank.

Diminishing Returns

The Smoke Sector, beneath the Crown Sanctuary · an unknown duration

Usage of the higher processes has fallen for six consecutive seasons, and perhaps a dozen people on the planet would notice if the part of him that used to think stopped being maintained. It reads, almost, like relief.

The Star Drifter

Earth departure · the crossing · the founding decades · Book Three

A second vessel, privately built and privately crewed, following the Ark-Genesis across the crossing. Not on the manifest and not under the Accord being written aboard the big ship — which is the whole point of it.

The Forty

Aboard the Ark-Genesis · Years 0–2 after the Handoff

Forty of Vance's people in a tumbling twenty-mile hull for two and a half years with no tether and no way down. They are living inside the largest arsenal ever assembled and they never find out. The reader knows. They never do.

The Sworn

The deep-shaft network · four generations

Founding-era survey crews sworn to absolute secrecy and reassigned to maintain the deep shafts for life. Their children did the same work. So did theirs. How a secret survives a hundred and forty years without anybody guarding it.

The Space Pirates

Earth · a hundred and forty years

Calder never built one ship. He built hidden yards on every continent and left the swarm to run them — and for a hundred and forty years they have gone on building ships on a dying planet for a departure that already happened.

The Bots That Stayed

Earth · the century after departure

The companion piece, told from the ground. The stowage inventory came back one higher than the build required. They never malfunction. What goes wrong is a hundred and forty years of nobody cancelling anything.

The Sinks

The Venus Sector · four generations

Forty-five thousand people in a sector dug as a foundry and never designed as a habitat, on a rotation that was supposed to be temporary four generations ago. The constituency Book One liberated and never reached.

Assumptions I Am Making

Aura-Marina · sixty years

The woman who invented the method the entire series resolves on, and never held any power at all. Sixty years of careful work by somebody nobody was ever going to name, written as her own working notes.

Standing Tasks

One dwelling · Years 3–60 after the Handoff

One H.A.L.O. unit's operating runtime, from siting to an empty dwelling fifty-seven years later — told entirely as the document itself. No narrator, no interiority, not one feeling in it. The unit is the one Harlow refused, re-sited two dwellings along to an unledgered family who are in no public record anywhere, which makes this the only document in existence that says they were here. Complete — all 55 chapters drafted. Queued to begin the moment Book Two closes.

Banners And Wind

Ledger's End · nine years

A committee stood up for twelve days a year to hang the wiped debt across the spans and get it down again before the wind takes it — which nobody can cancel, because the holiday runs on arithmetic, and nobody can disband, because after the Handoff no body has the authority to disband anything. Nine years later it is the most competent standing body on the planet and not one person ever claimed a thing. A comedy, told by the clerk who wrote it all down.

Carried

The Touge Passes · forty Vigils

A few thousand people planet-wide who strap on ballast to live closer to a full Earth gravity, because they believe the built-in ease has made everyone soft — and they are right, and get no credit for it, because they arrived by faith instead of evidence. Then an implant arrives that solves the physical half of it completely and the spiritual half not at all. Forty Vigils, one route, four years.

Ghost-Built

The Long Five, aboard the Ark-Genesis · thirty-six years, plus a coda on the ground

Thirty-six years of transit, ten people awake, and one of them spent all of it in a cargo hold building a car a year out of salvage — then running it on the five miles of hull he claimed for himself. The last car he made is the only picture anybody on Aura-36 has ever had of him.
