Ethan Wallace spends most of his time fishing, and the rest of it sludging through his senior year in high school. Life is simple and sweet, until the afternoon he pulls something strange out of Lake Michigan—a mermaid. Suddenly, his entire world is turned upside down. Because he can't seem to stay away from this particularly alluring mermaid . . . even though it seems insane; even though people are starting to die in nasty ways out on the water. Figuring out what it all means, and escaping with his life, could prove to be the biggest challenge of all.
