The Treehouse Series: The 13-Storey Treehouse (Book 1)

Welcome to the world's most incredible treehouse! The 13-Storey Treehouse is the first book in Andy Griffiths and Terry Denton's hilariously wacky series, where the story is brought to life through a brilliant combination of laugh-out-loud text and fantastic cartoon-style illustrations.

Andy and Terry live in the world's best treehouse, and it is packed with things you won't believe! It features a giant catapult, a secret underground laboratory, a tank of man-eating sharks, and a marshmallow machine that follows you around and shoots marshmallows into your mouth whenever you're hungry.

But life in the treehouse isn't all snacks and catapults. You’ll have to watch out for the sea monkeys (and the monkeys pretending to be sea monkeys), avoid the giant mutant mermaid sea monster, and whatever you do, try not to get trapped in a burp-gas-filled bubble!

Well, what are you waiting for? Come on up!
