Overview
Escape into the wildest, tallest treehouse in children's fiction with this complete 13-book paperback collection from New York Times-bestselling author Andy Griffiths and illustrator Terry Denton. Best friends Andy and Terry live in a treehouse that keeps growing story by story, from a modest 13 levels up to a towering 169, adding bowling alleys, catapults, and secret labs along the way. Each brand new paperback delivers rapid-fire jokes and laugh-out-loud chaos as the duo races to finish their latest book before their editor's deadline. Perfect for ages 7-11 (Grades 2-6), it's a set built for rereading and passing along to the next reader.

About the Books
This complete 13-book collection follows the same wonderfully absurd premise across every installment: Andy and Terry live in a treehouse that is never quite finished, and every new title adds another 13 storeys packed with fresh gadgets, mishaps, and running jokes. The set begins with The 13-Storey Treehouse, where the boys juggle a looming manuscript deadline while building out their first levels, and escalates all the way to The 169-Storey Treehouse, the thirteenth and final entry, which piles on the biggest additions yet. Along the journey, readers meet an ever-growing cast of oddball neighbors, quirky animals, and unexpected visitors who keep dropping by uninvited. Terry Denton's busy, cartoon-style illustrations appear on nearly every page, turning each book into a hybrid of graphic novel and traditional story that keeps reluctant readers turning pages. Andy Griffiths' trademark comic voice, full of wordplay and meta jokes about writing the very book you're reading, has made the series a favorite read-aloud and independent-reading choice alike. Because each volume follows a similar structure, first-time readers can jump in anywhere, though following the storeys in order from 13 up to 169 gives the fullest sense of how the treehouse, and the boys' friendship, keeps expanding. Themes of teamwork, creativity, and turning last-minute panic into inventive problem-solving run through every book. The set is ideal for classroom libraries, road trips, or a rainy-day binge, and its consistent length and tone make it easy for young readers to build real reading momentum, one storey at a time.
