Even though she's on vacation at the beach, young wizard Nita is still on active duty, available to assist any other wizard in distress. So when Nita meets the wizard S'reee, she is bound to promise help. Nita is needed to face the Lone Power, who is threatening life in the oceans. But although S'reee is a wizard, she is also a whale. Nita will need to shapeshift into a sea creature to join her. And when Nita learns that the final confrontation will take place 16,000 feet below the surface of the Atlantic Ocean, she begins to get uneasy. Explaining day-long absences to her curious parents will be tricky, too. Diane Duane's Wizardry books are marvelous combinations of fantasy, fast-paced adventure, and realism. As Nita crafts spells and prepares for what could be the ultimate sacrifice, you'll be pulled into her wondrous world. Christina Moore's vivid narration brings out the suspense and magic of each moment.
