Sometimes the difference between reality and insanity is only a matter of absurdity. There is nothing Milo Bishop fears more than the thought that he is going insane. Having grown up hearing his Uncle Jay's stories about the strange mermaids Milo never had a reason to believe they were actually true. But when a near-death experience gives Milo a vision of a mermaid calling to him for help, Milo is forced to test his uncle's claims. And when he winds up in Rasulka, the mermaid community tucked away, deep under the southern California seas, the question of his uncle's sanity is the least of his concerns. For in the heart of Rasulka, a growing whirlpool in the ocean-sky and the terrarium's changing climate -- along with a discarded prophecy that says their end will come when humans appear -- all suggest that the end is near. Along with his uncle and best friend, Moss, and Eluia, a young mermaid who grew up hearing myths about humans, Milo has only hours to sort through his doubts and insecurities and face down unimaginable terrors if he is going to find his way home -- before Rasulka, and everyone in it, is lost forever.
