May feels her life drying up. The sea calls to her, but her parents forbid her from swimming. She longs for books, but her mother finds her passion for learning strange. She yearns for independence, but a persistent suitor, Rudd, wants to tame her spirited ways. Yet after her fifteenth birthday, the urge to break free becomes overpowering and May makes a life-changing discovery. She does not belong on land where girls are meant to be obedient. She is a mermaid--a creature of the sea.
