Eleven-year-old Isabel is a “plain old” girl living in Provincetown, Massachusetts, who believes that she is destined to accomplish something special. When her fifth-grade class goes on a whale-watch field trip, something amazing happens: Dozens of different species of whales surround the boat, bumping the deck and sending Isabel flying into the ocean. Isabel is shocked to hear the whales speaking to her—she is a mermaid, they tell her, a “Chosen One” who has the ability to turn from a human into a whale and back again. She is destined to live among the whales long enough to learn their ways, and teach them about the human world. <br><br>Living among her pod is fun, at first, but Isabel has an important mission. She will change the whales' future forever, and learn a lot about herself in the process.<br><br><br><i>From the Hardcover edition.</i>
