About this book
Andy and Terry’s ever-expanding treehouse now has 39 wild levels, from a chocolate waterfall to a volcano marshmallow roaster and a jet-propelled swivel chair. When their latest adventure collides with a very unhelpful inventor, the boys have to think fast and work together to save the day. Packed with cartoons, short chapters, and nonstop silliness, this is a perfect pick for readers who like humor and high-energy action. Great for ages 8–12 who are moving into longer books but still love lots of illustrations.
Setting: a fantastical multi-level treehouse in a contemporary world
