If she could, Shelly would live in the sea. Better to be a fish than to live the way she does: her parents divorced, she doesn’t know anyone at her new school, and she even lost the last swimming competition. But now she has friends! It doesn’t matter that the girls think Shelly is a know-it-all and even (can you believe it!) made her throw a plastic coffee cup into the ocean. That’s where everything started. First, Shelly was carried away by a wave—and then real miracles began: in her dream she ended up in a cave with a sea witch. The witch promised to grant the girl a wish… but it all went wrong. Completely wrong. Terribly wrong. What’s happened to her hands? And why is it so hard to breathe? What deal did she make with Ursula?
