Rex, Dinosaur in Disguise Series

by ,
(29 reviews)

This full colour, fully illustrated chapter book series is the perfect stepping stone for moving from picture books to independent reading. Plus, it's absolutely hilarious AND is about dinosaurs. 

Imagine if dinosaurs lived to tell the tale. Rex is one of them, and he must stay undercover if he wants to avoid ending up in the zoo or -- worse -- in a museum. With the help of none other than Bigfoot, Rex slowly integrates into society, and soon enough, he's making friends and going on daring adventures (yes, even into space!).

Whether your child is as obsessed with dinosaurs as ours or they just want something funny to read, we think the Rex books are a brilliant options, as well as our favourite Fiction and Non-Fiction books for kids who love dinosaurs.

All the Rex, Dinosaur in Disguise books in order:

Book 1: Dinosaur in Disguise (2022)
