The 39-Storey Treehouse, by Andy Griffiths, Illustrated by Terry Denton

 “This was a very funny book. It's about two boys called Andy and Terry who live in a 13-storey treehouse. They invent things and write stories. Andy does the writing and Terry does the drawing.” The Guardian.

Andy and Terry's amazing treehouse has a chocolate waterfall you can swim in, a volcano for toasting marshmallows, a not-very-merry merry-go-round,a disco with light-up dance floor,  and the world's scariest roller coaster. 

"This book is a recipe for reading fun—whipped up masterfully by author Andy Griffiths and illustrator Terry Denton." – Bookpage
