"A basic yet complete presentation of how to plan, design, and build a safe, fun treehouse structure for children"--Provided by publisher.

The magic tree house takes Jack and Annie to Africa where they meet up with wonderful wild animals, a very hungry warrior, and where they even solve a riddle.

The magic treehouse whisks Jack and Annie back to the days of deserted islands, secret maps, hidden gold, and nasty pirates.

Jack and his younger sister take a trip in their tree house back to ancient Egypt, where they help a queen's mummy continue her voyage to the Next Life.

Jack and Annie are joined by Teddy and Kathleen as they travel to the snowy Land-Behind-the-Clouds, where they search for the eye of the Ice Wizard and attempt to help Merlin and Morgan.

Join Andy and Terry in their now 91-storey spectacular treehouse (It used to be a 78-story treehouse, but they keep getting ideas for more stories!). They've added 13 new levels, including the world's most powerful whirlpool, a mashed-potato-and-gravy train and a human pinball machine. Why not try your luck on the spin-and-win prize wheel or hang out in a giant spider web (with a giant spider), or you can always get your fortune told by Madam Know-it-all...

Who wouldn't want to live in a treehouse? Especially a 13-story treehouse that has a bowling alley, a see-through swimming pool, a tank full of sharks, a library full of comics, a secret underground laboratory, a games room, self-making beds, vines you can swing on, a vegetable vaporiser and a marshmallow machine that follows you around and automatically shoots your favourite flavoured marshmallows into your mouth whenever it discerns you're hungry....

Jack and Annie travel in their Magic Tree House back to a Hawaiian island of long ago where they make friends, learn how to surf, and encounter a tsunami.
