Nobody gets why Casey's upset. She's just been informed that she's spending the ENTIRE summer on some deserted tropical island with her father, his new wife, and her two brothers. Her father will study the endangered sea turtle, her brothers will drive her crazy, and Casey's sure she will die of boredom while dreaming of all the fun she could have been having with her friends back home.

But Tartuga turns out to have its charms--particularly a cute boy Casey's age named Jonah. And spending so much time away from cell phones and emails give Casey the unexpected chance to listen to herself. But when a tropical storm bears down in Tartuga and Casey's father can't make it back in time, will Casey be able to pull it together and save Paradise for all of them?
