BOOK DESCRIPTION: The #1 bestselling Magic Tree House series for chapter book audiences is ready to whisk you away across the world with Jack and Annie—this time to save sea otters after a shark attack! Magic Tree House is the perfect series for kids ready to transition from leveled readers and picture books to longer novels!
It’s bright and early when the magic tree house spins Jack and Annie to Monterey Bay, California. It’s their mission to collect sea urchins in the underwater kelp forests! But they know nothing about collecting sea urchins—can a grouchy boat captain help them? Maybe. But Jack and Annie have another problem when Annie finds a badly injured sea otter. They’re not supposed to help the otter. . . but it’s the right thing to do. Can they convince the grouchy boat captain to help them?
