Fierce, seductive mermaid Syrenka falls in love with Ezra, a young naturalist. When she abandons her life underwater for a chance at happiness on land, she is unaware that this decision comes with horrific and deadly consequences. Almost one hundred forty years later, seventeen-year-old Hester meets a mysterious stranger named Ezra and feels overwhelmingly, inexplicably drawn to him. For generations, love has resulted in death for the women in her family. Is it an undiagnosed genetic defect . . . or a curse? With Ezra's help, Hester investigates her family's strange, sad history. The answers she seeks are waiting in the graveyard, the crypt, and at the bottom of the ocean - but powerful forces will do anything to keep her from uncovering her connection to Syrenka and to the tragedy of so long ago.
