About the Magic Tree House Fact Tracker series
The Fact Trackers are the nonfiction companion line to Magic Tree House: each one answers the real-world questions raised by a specific fiction adventure -- when dinosaurs lived, how sharks hunt, what really happened aboard the Titanic -- with photographs, illustrations and kid-friendly explanations tied directly to the topic Jack and Annie just visited. Mary Pope Osborne co-writes every volume: her husband Will Osborne co-wrote the first eight titles (Dinosaurs through Twisters and Other Terrible Storms, 2000-2003), her sister Natalie Pope Boyce took over as co-writer starting with Dolphins and Sharks (a transitional volume crediting both) and wrote the bulk of the run through Llamas and the Andes (2020), and Jenny Laird co-wrote the most recent volume, Snow Leopards and Other Wild Cats (2022). Sal Murdocca, the fiction series' longtime illustrator, illustrated many of the earlier Fact Trackers before Carlo Molinari and then Isidre Mones took over illustration duties on the later volumes.
Each Fact Tracker is numbered to match a specific Magic Tree House adventure and is designed as optional further reading -- kids don't need to read them to follow the story, but they turn a young reader's curiosity about a topic the fiction only touched on into a proper nonfiction deep dive.
