Tania Sanchez can barely juggle studying for SAT's and training for the biggest surfing competition of her life. Her one escape involves fantasizing about living as a mermaid. It's not until she wipes out on her board and is rescued by one that she actually believes her fantasy is far more possible than she ever dreamed. Events are further complicated when she learns she has to compete against her friend and mentor, Caleb. Tania doesn't know how to tell Caleb how she really feels, especially when she starts falling for her new mer-friend, the one with red skin who might need a bit of rescuing, too.
