The 91-Storey Treehouse
Best friends Andy and Terry live in an incredible treehouse that is now 91 storeys high! There's every type of room you can imagine - pinball machine, world's most powerful whirlpool, giant spider web - and also a mysterious red button that they can't decide if they should push or not.
Andy and Terry are asked to babysit their publisher's grandchildren, which seems easy enough. But the kids want to explore the treehouse and manage to get themselves into heaps of trouble, especially when everyone gets sucked into the whirlpool.
Perfect for readers of Diary of a Wimpy Kid who want an easy, funny read, the Treehouse series is full of laugh-out-loud mayhem. This is the seventh title in the series, but can easily be read on its own – although once you start this series, you're unlikely to stop.
