The 52-Storey Treehouse is the fourth book in Andy Griffiths and Terry Denton's wacky treehouse adventures, where the laugh-out-loud story is told through a combination of text and fantastic comic book-style illustrations.

'The kind of book I would have loved as a kid' – Tom Fletcher, author of The Danger Gang

Andy and Terry's incredible, ever-expanding treehouse has thirteen new storeys! It used to be 13, then 26, then 39, but they keep expanding!

This time, there's a new watermelon-smashing level, a wave machine, a life-size snakes and ladders game (with real ladders and real snakes!), a rocket-powered carrot launcher, a Ninja Snail Training Academy and a high-tech detective agency with all the latest high-tech detective technology. Which is lucky, because they have a BIG mystery to solve: where is Mr Big Nose?!

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