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

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

The table net-caster, and the range card you paint on it afterwards.
Household junk, numbered steps, under thirty minutes, and a number the child writes down at the end.

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.
Questions about this one
Eight answers,
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.
