"A Stepping Stone Book."
N2  - Travel with Jack and Annie to the deep, dark ocean to encounter the stealthiest of underwater predators: the shark! Jack and Annie are going on vacation! Or so they think. Teddy, the young sorcerer, has promised them a relaxing time off the coast of Mexico. The magic tree house whisks them away to a beautiful sandy beach, and Jack and Annie are ready to raft on the ocean waves. But when a hungry shark attacks, their dream vacation turns into a nightmare!
