The journey, scene by scene
Every copy of Lost in Dino Valley follows these 13 scenes in order. The scenes are fixed — the words are written for your child, and their hero is drawn into every one.

- ferns and prehistoric trees
- an open meadow with grazing dinosaurs
- a distant smoking volcano
- a wide river with lily pads
- a nest with a crying baby dinosaur
- fleeing between rocks with motion lines
- a ledge with a reaching hand
- a nest with a mother dinosaur

How your child becomes the hero
You enter a first name, an age and pronouns, then design a cartoon avatar — skin, hair, outfit and more. That exact character is drawn into all 13 pages by code, so the hero on the first page is identical on the last. No photo uploads, ever.
The words are written fresh for your child: an AI language model writes the book’s title and one line of story text per scene — and nothing else. The artwork is pre-drawn, the scenes are fixed, and no image-generation AI is involved. The same story is also available as a coloring book, drawn as line art to fill in.
