You know that feeling when you walk into a library or a used bookstore and see a literal wall of those thin, brightly colored paperbacks? It’s overwhelming. Mary Pope Osborne didn't just write a series; she built a universe that has been expanding since 1992. If you're looking for a magic tree house book list to help a kid (or yourself) navigate the adventures of Jack and Annie, you aren't just looking for titles. You’re looking for a map.
Most people don’t realize there are actually three distinct "branches" of this tree. You have the original adventures, the more complex "Merlin Missions," and then the non-fiction "Fact Trackers." It’s a lot.
Honestly, the sheer volume of these books—over 100 if you count the spin-offs—is why they still dominate elementary school classrooms. They work. They're basically the "gateway drug" to reading. Jack is the studious, notes-taking nerd we all secretly are, and Annie is the impulsive one who usually gets them into trouble (and then out of it).
Why the magic tree house book list is actually three lists in one
If you just grab a random book off the shelf, you might end up with Dinosaurs Before Dark (Book 1) or you might accidentally pick up Hurricane Heroes in Texas (Book 30 of the sequel series). The reading level jump between those two is actually pretty significant.
The core of the franchise is the original series. These are the short ones. We’re talking 60 to 80 pages with big font and lots of illustrations. They are perfect for seven-year-olds who are just moving away from picture books. These first 28 books follow a specific pattern: Morgan le Fay, the librarian of Camelot, sends the kids on missions to collect books or save stories.
The Merlin Missions: Stepping up the game
Around book 29, things change. The series rebranded as "Merlin Missions." Jack and Annie get older—sorta—and the books get longer. These are often twice the length of the originals. They involve higher stakes, more magic, and deeper mythology. If you have a child who finished the first 28 and is begging for more, this is where you go next. You'll notice the numbering often resets or gets confusing in newer editions, but generally, Christmas in Camelot is the threshold.
Don't forget the Fact Trackers
Then there are the "Fact Trackers." These are the non-fiction companions. Mary Pope Osborne writes these with her husband, Will Osborne, or her sister, Natalie Pope Boyce. They take the historical or scientific theme of a fiction book—say, the Titanic or Ancient Greece—and give you the real-world history.

The Original 28: Where the Magic Started
Let’s be real. You have to start at the beginning. If you don't read Dinosaurs Before Dark, you miss the discovery of the tree house in the Frog Creek woods.
- Dinosaurs Before Dark (The Pteranodon adventure)
- The Knight at Dawn (Castle life and secret passages)
- Mummies in the Morning (Ancient Egypt)
- Pirates Past Noon (Cap'n Bones and treasure maps)
This first "quartet" establishes the formula. Jack takes notes in his backpack. Annie talks to the animals. They find a "M" medallion. It’s simple, it’s effective, and it’s fast-paced.
The list continues through various historical eras. You’ve got Night of the Ninjas (Book 5), which is a huge fan favorite because, well, ninjas. Then Afternoon on the Amazon (Book 6), and Sunset of the Sabertooth (Book 7). By the time you get to Midnight on the Moon (Book 8), the mystery of who "M" is finally gets solved. (Spoiler: It’s Morgan le Fay).
What’s interesting about the magic tree house book list is how it groups books into four-story arcs. For example, books 9 through 12 focus on Jack and Annie solving riddles to become Master Librarians.
- Dolphins at Daybreak
- Ghost Town at Sundown
- Lions at Lunchtime
- Polar Bears Past Bedtime
If you’re a parent or teacher, buying these in "sets" of four usually makes the most sense because the overarching plot resolves every fourth book.
Navigating the Merlin Missions and Beyond
After the initial 28, the series takes a turn into the fantastical. Merlin the Magician starts giving the orders instead of Morgan. These stories are a bit more "Lord of the Rings" lite.
The titles get more descriptive too. Summer of the Sea Serpent (Book 31) or Night of the New Magicians (Book 35). This is where the magic tree house book list starts to incorporate more cultural figures. Jack and Annie meet Louis Armstrong in A Good Night for Ghosts and Leonardo da Vinci in Shadow of the Woods.
The series eventually dropped the "Merlin Mission" branding for newer releases, moving back into a numbered sequence that continues well into the 60s. For instance, Late Lunch with Llamas (Book 34 in some counts, but part of the continued legacy) keeps the spirit alive for a new generation of readers who grew up with iPads instead of VCRs.
Common Misconceptions about the Order
People often get tripped up because the publishers recently re-numbered the books. They took the Merlin Missions (which used to be numbered 1-27 separately) and folded them into the main sequence. So, if you see Big Day for Baseball listed as Book 29, but your old copy says Merlin Mission #1, don't panic. It's the same book. The "new" numbering is now the standard to keep things "simple," though it arguably made things more confusing for used-book hunters.
The Secret Sauce: Why These Books Rank
There is a reason you see these books in every classroom. Osborne hits a very specific "Lexile" level. The vocabulary is challenging enough to teach new words—like "amphitheater" or "pith helmet"—but the sentences are short enough that a struggling reader won't give up.
It’s also about the "Jack and Annie" dynamic. Jack is the cautious researcher. He represents the "academic" side of reading. Annie is the "emotional" side. She empathizes with the mammoths and the orphans. Together, they model how to process information.

Finding Rare or Special Editions
If you are a collector, the magic tree house book list gets even weirder. There are "Special Editions" that include extra facts. There’s a musical (yes, really). There’s a graphic novel series started recently that adapts the original stories into a comic format. The graphic novels are a godsend for visual learners who find the walls of text in the original paperbacks a bit daunting.
A Quick Cheat Sheet for the Major Arcs:
- Master Librarian Arc: Books 9–12.
- Research Lab Arc: Books 13–16 (Where they save stories from ancient libraries).
- Mystery of the Enchanted Dog: Books 17–20 (Teddy the dog!).
- The Dragon of Fortune: This is where the mythic elements really peak.
Practical Steps for Parents and Educators
If you're looking to dive into the world of Frog Creek, Pennsylvania, don't just buy a random box set. Follow this roadmap to save money and keep your reader engaged.
Start with the "Starter Set" (Books 1-4).
Don't commit to the whole 60+ book run yet. See if the kid likes the "fact-finding" aspect. If they are obsessed with the dinosaurs in Book 1, immediately grab the Dinosaurs Fact Tracker. It builds a bridge between fiction and reality.
Check the "New" Numbering.
If you are buying used books on eBay or at thrift stores, look at the cover style. The "classic" covers are by Sal Murdocca. The newer ones have a more modern, digital feel. If you want a matching set, stick to one cover style, as the numbering differs between the 20th-anniversary editions and the originals.
Listen to the Audiobooks.
Mary Pope Osborne narrates many of these herself. Her voice is exactly how you’d imagine a magical librarian’s voice to sound. It’s great for car rides and helps kids with pronunciation of the harder historical names.
Use the "Magic Tree House Kids' Adventure" website.
It's surprisingly robust. They have "Passport" programs where kids can earn stamps for books they’ve read. It turns the magic tree house book list into a game, which is the ultimate hack for getting kids to read more.

The beauty of this series isn't just in the magic or the time travel. It's in the consistency. For over thirty years, Jack and Annie have been the most reliable tour guides in children's literature. Whether they're dodging volcanoes in Pompeii or drinking tea in Victorian London, the formula works.
If you're starting this journey, start small. The tree house is always there, and the door is always open. You just have to point to a picture and wish you could go there.
Actionable Insight:
To build a sustainable reading habit, use a "paired reading" strategy. Pick one fiction title from the magic tree house book list and its corresponding Fact Tracker. Read the fiction book first to spark interest, then use the non-fiction book to answer the "Is that real?" questions that inevitably crop up. This reinforces reading comprehension and introduces the concept of cross-referencing sources at a young age.
