Are you ready to embark on a whirlwind journey through time and space with Jack and Annie? The Magic Tree House series by Mary Pope Osborne has captivated young readers for decades, blending history, science, and fantasy into bite-sized adventures that educate and entertain. If you’re a parent looking for the perfect chapter books for your kids, a teacher seeking classroom reads, or even an adult revisiting childhood favorites, you’ve come to the right place. In this guide, we’ll break down the Magic Tree House books in order, including the main series, Merlin Missions, Super Editions, and Fact Trackers. Let’s dive in and discover why this series has sold over 134 million copies worldwide!
What Is the Magic Tree House Series About?
The Magic Tree House follows siblings Jack (the cautious bookworm) and Annie (the bold explorer) who discover a mysterious tree house in the woods near their home in Frog Creek, Pennsylvania. Filled with books, the tree house magically transports them to different historical periods, mythical lands, and even outer space. Each book tackles a new mission, often involving solving riddles, helping historical figures, or learning about wildlife and cultures.
What makes the series so engaging? It’s not just the thrill of time travel—Osborne weaves in real facts, making every story a sneaky lesson. Kids aged 6-9 love the short chapters, illustrations by Sal Murdocca, and cliffhanger endings that beg for “just one more book!” Plus, the series grows with its readers: early books are simpler, while later ones add more complexity.
How Many Magic Tree House Books Are There?
As of October 2025, there are over 67 fiction books in the core series (including Merlin Missions), 1 Super Edition, and 44 Fact Trackers (non-fiction companions). The series started in 1992 and shows no signs of stopping, with new releases keeping the magic alive.
For the best experience, read in this order: the original 28 books, then the 27 Merlin Missions (a spin-off with more advanced plots), followed by the continuation of the main series starting from the “new” #29. This sequence follows the story’s progression, as Jack and Annie’s quests build on previous adventures.
