Two popular storybook titans, princesses and dinosaurs, battle to determine who should star in this laugh-out-loud picture book for fans of Shark vs Train and The Book With No Pictures.

This is a princess book!

No, it's a dinosaur book!

No, it's . . . a T. rex book? A dragon book? A rubber ducky book?!

From Linda Bailey, award-winning and critically acclaimed author, and Joy Ang, Adventure Time-artist and illustrator of the Mustache Baby series, comes an irresistibly irreverent picture book in which plucky princesses and determined dinosaurs have a battle royale over whose book this is. When they start calling in the big guns — or rather, the big carnivores — and decide to build a wall to resolve their differences, princesses and dinosaurs alike learn a thing or two about open-mindedness and sharing.

An argument ensues about what kind of book this is, a princess book or a dinosaur book. Maybe it is a book for everyone"--Provided by publisher.
