The Merlin Missions series is a magical extension of Mary Pope Osborne’s Magic Tree House books, perfect for readers aged 7–10 who are ready for longer, more complex adventures. In this spin-off, Jack and Annie are sent on quests by the wizard Merlin, often involving fantasy, mythology, and magical creatures—like rescuing a unicorn or helping Leonardo da Vinci.
There are 27 Merlin Missions in total—almost as many as the original series! Although they were originally numbered as part of the same series, they were later rebranded to help readers track Jack and Annie’s more magical adventures separately.
What’s different from the original series?
These books are longer, with more advanced vocabulary and a stronger fantasy focus. While the original series leans into history, the Merlin Missions blend historical settings with legendary and magical elements.
Reading level?
Ideal for children moving beyond early chapter books, with Lexile levels around 500L–700L.
Comparable reads?
Great for fans of Beast Quest and kids who love fast-paced fantasy adventures.
