It’s a dream vacation for Jack and Annie—or is it? When Teddy, a young sorcerer, offers to send Jack and Annie on a dream vacation, they can’t wait to go. The brother-and-sister pair wish for a trip to a beach paradise, and the magic tree house whisks them off to the coast of Mexico. Everything starts out perfectly as they raft around a coral reef. But then a hungry shark attacks! And their dream vacation turns into a nightmare!

Formerly numbered as Magic Tree House #53, the title of this book is now Magic Tree House Merlin Mission #25: Shadow of the Shark.
