Dinoroost · Book One of ten

Signal Green

Three years after every grown-up vanished, a thirteen-year-old has to walk five tons of dinosaur home across a flooded road in the dark.

The old world came back up through the new one, and the kids who were left built a village in the treetops.

Lars Vantén is thirteen, and the thing he is best at in the world is standing still. When nine hundred pounds of dinosaur locks onto a splitting gate post and will not stop, Lars walks out in front of it with his hands empty and low, says his own name until the sound of it is boring, and does not move his feet for thirty-one minutes — and the whole village claps. He is also the boy who says yes to everybody. Yes to the rope, yes to the ladder, yes to the kid who needs a witness at noon. His best friend is a hip-high raptor called Bramble, who steals exactly one boot from whoever Lars is talking to and always leaves something in its place.

Then he promises the same afternoon to two people, and picks wrong. A five-ton Stegosaurus walks out over the mud shelf with a squall coming and stops on a traffic island three-quarters of a mile from the gate. That night the river comes up fourteen feet, the causeway goes under three feet of moving water, and the only person in the valley who can walk out there is the boy everybody already asked for something else.

The spotlight

Lars Vantén

13, Rider

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. 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.

In the back — Field Notes

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

Deinonychus

Deinonychus — quill knobs on a catalogued forearm bone, and the claw experiment that showed it hooked rather than sliced.

Inside this one

Eighteen drawings,
one a chapter.

Each one is the object that chapter turns on, at the head of the chapter, in a single ink. All eighteen are here — nothing about this book is behind a Look Inside button.

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.
Chapter 1
Ink drawing. A single chipped enamel mug standing alone and upright, seen from just above the rim's height.
Chapter 2
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.
Chapter 3
Ink drawing. A salvaged bicycle frame with the back wheel removed, bolted down through deck planks by flat steel straps, its pedals and chain still on it.
Chapter 4
Ink drawing. A dinosaur harness laid out flat and in order on the ground as it came off the animal: a wide chest strap with a heavy buckle, two shoulder straps.
Chapter 5
Ink drawing. A long coil of wet rope fallen loose among the buttress roots of a huge tree, the rope in slack irregular loops where it landed.
Chapter 6
Ink drawing. A wire milk crate holding six wooden spools of kite line of different sizes, the line wound unevenly.
Chapter 7
Ink drawing. The bare scaled feet and lower shins of a small feathered dinosaur, planted and stopped dead.
Chapter 8
Ink drawing. Three thick hand-bound books of different sizes stacked and strapped together with one worn leather belt through the buckle, corners bumped.
Chapter 9
Ink drawing. One plain worn metal spoon, clean and empty, lying alone on a scrubbed plank table, a small notch cut into the end of its handle.
Chapter 10
Ink drawing. A small flat-bottomed punt afloat, seen close and square-on from the side, riding low, its patched planking and one paint repair showing.
Chapter 11
Ink drawing. A weathered wooden stake driven upright, nails hammered into it in an uneven vertical line up its length.
Chapter 12
Ink drawing. A rough animal stall built from mismatched wooden pallets and one salvaged farm gate on a bad hinge, seen square-on.
Chapter 13
Ink drawing. A dented tin fat-lamp with a wire bail hung on a nail beside the edge of a shut plank door, its small flame burning, the door's iron latch below it.
Chapter 14
Ink drawing. A length of rope running through a closed fist, the rope coming in slack on one side and leaving taut on the other.
Chapter 15
Ink drawing. A single leaning steel post standing in shallow moving water with nothing on top of it, the bolt holes where a sign was empty.
Chapter 16
Ink drawing. One small bare shrub, the last of nine, standing alone in shallow standing water that comes up over the lowest few inches of its stems.
Chapter 17
Ink drawing. A flat tobacco tin with its lid open, wired to a wooden handrail by twisted fence wire, one short worn stub of chalk lying in the tin.
Chapter 18

from this book’s own file.

Every one of these is a fact out of the manuscript or the catalogue rather than a sales line — the measured word count, the drawings that actually exist, the animal on the nonfiction page at the back.
