A boy carrying a lantern walks beside a Stegosaurus through shallow gold water at sunset, a small feathered dinosaur at his knee and rope bridges strung between huge trees behind them.

Season One · The Nine Minutes · ten books

Every grown-up
on Earth vanished.
The kids kept
the dinosaurs.

Ten adventures for readers nine to twelve, about a village lashed into seven enormous trees over a drowned town — where nobody tames a dinosaur, and a dinosaur is asked.

All ten, and the ten ebooks free with them. Ships free in the US.

The season, in order

One season.
Ten episodes.
Read in order.

A book is an episode. One concrete problem — water, salt, a herd, a signal — solved with rope, nerve, animal sense and friends, in about twenty-one thousand words, which is a two-hour read. Each volume puts one of eight kids at the center and gives the others work to do around them. Ten make a season, and they are built to be read in order: the same forty kids, the same animals, the same bell code running under all ten, and a village that keeps a written count of everything it has — so what one book spends, the next one is short of.

What it is

Nine minutes,
and then deep time.

Every grown-up on Earth vanished in nine minutes, deep time came up in their place, and the kids who were left built a village in the treetops and asked the dinosaurs for help — and on your sixteenth birthday, you vanish too.

On an ordinary Tuesday the sky went pale for nine minutes. When it cleared, everyone older than sixteen was gone — not dead, gone, cars still idling and bread still rising. Then the old world came up through the new one: horsetail to the second floor, the animals of a hundred million years ago simply there. The kids call it the Overgrowing.

Three years on, thirty-nine children live in seven impossible trees over a drowned river city. Rope bridges, salvaged neon, a cargo lift worked by a Triceratops, a bell cut from a fire truck’s brake drum. They are not surviving. They are thriving, and that is the fantasy. Four miles downriver, a hundred and twelve kids in a flooded ballpark shock-collar their animals and keep an account of what everyone owes. That place works too. That is the problem.

Shelf
For a reader who finished Camp Cretaceous and wanted more of it; who reads The Last Kids on Earth for the funny bits; or who has looked at Dinotopia for an hour and wished somebody lived there.

Seven enormous araucaria trees standing in shallow brown floodwater, hung with patched cabins on stacked platforms, rope bridges strung between them, crates and lanterns on pulleys, and the roofs of drowned houses and a car showing above the water below.
The Roost. Seven hushpines that came up through a drowned river city, sixty-one platforms, and thirty-nine kids living on them. The lift is worked by a Triceratops on a treadwheel, and the bell is a fire truck’s brake drum.

Painted on the bell rail, ninety feet up

Three sentences,
in white house paint.

Every one of the ten books quotes one of them flat and then turns on it. Spoken, they are three short sentences that end arguments.

Law One

No rig points at a person.

“Point it down.”

Law Two

No dino carries a fight it did not choose.

“Not her fight.”

Law Three

Nobody goes Quiet alone.

“Not alone.”

How this world works

Bramble, a Deinonychus the size of a large dog, feathered, standing alert.

A dino is asked

Nobody here tames a dinosaur. A dinosaur is asked. You sit in its weather for nine days or a whole season and do nothing, then kneel at the shoulder line with your hands open and empty, say your own name, and say out loud what you are asking for. The answer is yes, no, or not-yet, and not-yet is the usual one. The bond is a Match, which means the animal chose too and can un-choose: it walks its rig back to the platform and leaves it there. In three years that has happened four times.

A rig laid out in order: webbing, buckles, a padded hip seat, and a single tapered release pin on a lanyard.

Rigs, not weapons

A rig is harness gear an animal wears and helps operate — a net-caster on a Triceratops frill built around a diner’s lazy-susan bearing, a water cannon geared off an Ankylosaur’s tail swing. Every one of them comes off the animal itself, with no person and no tool, in about a second. That is the Cast-Off, and the first thing a Matched animal is taught is how to shed it. Riding comes second. Nothing a rig fires is meant to hurt anybody: nets, sap, mud, sound, rope, smoke, flares — never bullets, never blades, never fire.

A flooded ballpark under floodlights, its stands converted into housing, where a hundred and twelve children keep an account of what everyone owes.

Two villages

Four miles downriver a hundred and twelve kids live in a flooded ballpark, shock-collar their animals and pay each other in plastic drink tokens. That place works too, and that is the problem. The Tally builds weapons. The Roost builds tools. That difference is the whole show.

The code the books run on

The bell.

A fire truck’s brake drum at ninety feet, struck with a brass hammer on a jump-rope lanyard. It carries four miles downriver, which is exactly as far as the other settlement, and both sides know it.

Anybody may ring it. No permission, no age, no exception. It is not one of the Laws. It is the closest thing the Roost has to a fourth.

The bell: a fire truck's brake drum, red paint worn to rust, hung by a chain from a timber frame, with a brass hammer on a cord beside it.

It does not drift. Two bells means food in Book One and it means food in Book Ten, and the Triceratops on the cargo wheel stops walking at two bells in every single one. A few signals are held back here because they belong to volumes you have not read.

Eight kids, and the one from downriver

Everybody gets
one book.

Each volume puts one of them at the centre and gives the rest work to do around them. They stand here to scale, which is a fixed thing in this series: Odji is tallest, Tarn is widest, and Pia is smallest by a head and furious about it.

Book One

Lars Vantén

13 years old

Rider, and the boy who says yes to everybody. He is the only person here who swims, and he says I’ll get that nine times a day and means it every time.

Matched to Bramble, Deinonychus.

Book Two

Nell Okonjo

14 years old

Head Rigger. Seven pockets, one category per pocket. She can hear a bad bearing three platforms away and has never been wrong, and when Nell runs, everyone runs.

Matched to Boiler, Ankylosaurus.

Book Three

Odji Faal

15 years old

Keeper of the Ledger — every trade, every debt, every birthday, in three books strapped together. He will not Match, because he will not make an animal love somebody who is leaving.

Book Four

Kit Ossory

13 years old

Came up the river from the Tally in the best-made coat in the Grove, and stands at an angle to whoever is talking so the door stays over her shoulder.

Matched to Nine, Utahraptor.

Book Five

Pia Marchetti

9 years old

Runs the eleven Small and nine chicken-sized dinosaurs, out of a bucket holding snacks, string, a whistle, four beetles and a list. “I’m not little, I’m narrow. The difference is I fit.”

Matched to The Tick-Tocks, Compsognathus × 9.

Book Six

Tarn Beaufort

14 years old

Green — food, hands, heavy work. He carries the calorie count of the whole village in his head and does not share it, and he arrives at every argument with something to eat.

Matched to Holly, Parasaurolophus.

Book Seven

Wren Adeyemi

11 years old

Keeps the Ear: forty-one salvaged speakers on a rack over the water, powered by whoever is listening pedalling a bicycle. She takes the watch nobody else wants.

Matched to Parrot, Microraptor.

Book Eight

Mars Quintero

12 years old

Far-scout. Out two days, four, once nine, and back with routes, water and where the patrols are walking. She keeps the Far Map: thirteen feet of paper, board and painted canvas.

Matched to Kettle, Gallimimus.

The Tally

Corva Quist

15 years old

First of the Tally, four foot ten, and the only person in either settlement who sits down under your eye line to say the thing. She writes you a receipt afterwards.

And the animals that said yes

A Match is a
two-way thing.

The animal chose too, and it can un-choose — walk its rig back to the platform and leave it there. In three years that has happened four times.

Bramble, a Deinonychus the size of a large dog, feathered, standing alert.

Bramble

Deinonychus · Lars’s

The runt of his clutch and finished growing. A crooked outer toe ticks on plank decking, so the whole Roost always knows he is coming — and he will not put a foot in water.

Boiler, an Ankylosaurus, six tons and wider than a car, armoured and low to the ground.

Boiler

Ankylosaurus · Nell’s

Six tons and wider than a car. Three slow knocks of his club on the decking means open the gate, and he will not cross a bridge until he has watched a person cross first.

Holly, a Parasaurolophus, on all fours with the long curved crest laid back over her shoulders.

Holly

Parasaurolophus · Tarn’s

Eight feet of folded tube inside four and a half feet of crest, and a note that carries three miles over water. She counts the village’s children, and if one is missing she will not move.

Nine, a Utahraptor, eighteen feet long and feathered.

Nine

Utahraptor · Kit’s

Eighteen feet and an appallingly quiet lope. Named for the number off her old tag, kept so nobody gets to pretend it did not happen. She steals hats and wears them terribly.

The Tick-Tocks, nine Compsognathus about a yard long, each with a differently painted tail.

The Tick-Tocks

Compsognathus × 9 · Pia’s

A yard long, three pounds, mostly tail, each tail painted a different color of salvaged nail polish. One clicks and nine synchronise inside four seconds.

Parrot, a Microraptor with four feathered wings, black going blue-green in the light.

Parrot

Microraptor · Wren’s

Four wings and two pounds. He copies the bell, a door hinge and Tarn’s cough, always at the worst moment, and in rain he becomes a wet sock and sulks for hours.

Kettle, a Gallimimus, as tall as a horse and built to run.

Kettle

Gallimimus · Mars’s

Tall as a horse and steaming on cold mornings, which is the name. She will run all day, will not go through a doorway, and whistles about three seconds before she bolts.

Sunday, a small pterosaur with a six-foot wingspan and a diamond vane on the tail.

Sunday

Rhamphorhynchus-type · Mars’s

A six-foot wingspan and one destination in the world: she only ever flies home. Every scout carries her out in a basket to send anything back.

Signal Green · Cold Open

Vee Toomey was four, and she had the rule by heart, which was the only reason she was allowed in the boat.

“Count the logs before you cross,” Vee said, “and if a log has two knots on top, it is not a log.”

“Again.”

“Count the logs before you cross, and if a log has two knots on top it is not a log, and there should be more fish than this.”

“That last part isn’t in it.”

“It should be,” Vee said.

Pia let it go, because the child was not wrong. Day 1,096, and thirty lines in they had four catfish, a bullhead the size of a thumb, and somebody’s shoe.

They worked the street from the north end, where two feet of brown water stood over the sidewalk and the parking meters came up through it like reeds. Forty-one set lines, tied off to parking meters, railings, a fire hydrant and one drowned mailbox. They ran them every morning before breakfast and rebaited whether they had caught anything or not. The boy did the knots. Dot bailed with a paint can and nobody had to tell her. Vee was allowed to hold the fish. That was the whole of Vee’s job and she took it seriously.

The punt leaked out of one seam, politely. Behind them the Grove stood up out of the flooded blocks with its lamps still burning at a hundred and ninety feet. Nobody had gone up yet to put them out. Yesterday somebody had propped a door open up there and left it open all day. This morning it was shut again. That happened once a year, and Pia had stopped asking about it when she was seven.

“Line nine’s gone,” the boy said.

“Gone how?”

“Gone with the meter.”

“Write it on your hand.”

Going home meant crossing the mouth of the street, where the current came round the bank building and ran. Pia stood the pole up and looked, and counted, because that was what you did and it took no time at all.

Four logs. Five.

The sixth had two knots on top of it, an inch apart, and they were pointed at the boat. There was moss grown over the back of it, with a little duckweed in the moss.

Pia did not tell anybody to be quiet. Telling them would be noise. She put the pole down through the water instead of dropping it in, and pushed, and brought it back through the water instead of over it. They went across at the speed of a thing that is not going anywhere in particular. Vee explained to the bullhead why it was going to be eaten. The knots went by nine feet off the bow and did not turn.

At the landing she tied off and counted heads on the boards. Twelve.

Then she counted them again and got twelve.

That is the first page of the first book, exactly as it is printed.

What a chapter opens with

One drawing
per chapter.

Books One, Two and Three carry eighteen each, at the head of every chapter, of the object that chapter turns on. Books Four to Ten are text and cover for now, and everyone who buys one will be told when that changes.

Ink drawing. A thick climbing rope pulled taut, gripped in two boy's hands, one above the other, the fibres of the rope frayed and hairy.
Ink drawing. A single chipped enamel mug standing alone and upright, seen from just above the rim's height.
Ink drawing. A wet rope taken twice around the bottom rung of a rough wooden ladder and cinched, the rung worn shiny where the rope bears, the rope's tail hanging.
Ink drawing. Two lamps made from jam jars, each with a small flame in it, hanging by wire hooks from a taut bicycle brake cable.
Ink drawing. One short section of mismatched water pipe lying by itself, about four feet long, the three joints each made differently — a hose clamp.
Ink drawing. A hand-made balance beam by itself: a plain straight hardwood arm resting on a central knife pivot, a shallow pan hanging on three cords from each end.
Ink drawing. A long straight measuring pole standing upright by itself, notched across at intervals and burnt black in bands at the notches.

Field Notes

One real dinosaur a volume: how to say it, when it lived, two pieces of evidence a nine-year-old can check, and who found them.

Ten builds

Make It

Household junk, numbered steps, under thirty minutes, and a number the child writes down at the end. A siphon, a balance beam, a bull-roarer.

The whole world

The Roost

The places, a day from grey light to lights out, the bell code, how to say every name out loud, and what every word in the books means.

The byline

The Ledger: three worn books strapped together with a belt, a pencil pushed under the strap.

Jory Hark is a pen name.

The person behind it writes for film and television, and would rather these books were read without that standing in front of them.

What the day job left behind is the shape. Dinoroost is built the way a season is built: ten episodes, one spotlight character each, a cold open in front and a tag behind, a midpoint that takes something away and never gives it back, and a clock running under all ten that nobody in the story can stop. The chapters are assigned their lengths before they are written, the way scenes are, because a scene that runs long is not a longer scene, it is a worse one.
