The story of the Sea Witch, the villainess from Hans Christian Anderson's classic tale The Little Mermaid, told from the viewpoint of the Sea Witch when she was a twelve-year-old girl. Ever since her best friend Anna died, Evie has been an outcast in her small fishing town. Hiding her talents, mourning her loss, drowning in her guilt.Then a girl with an uncanny resemblance to Anna appears on the shore, and the two girls catch the eyes of two charming princes. Suddenly Evie feels like she might finally have a chance at her own happily ever after. But magic isn't kind, and her new friend harbors secrets of her own. She can't stay in Havnestad--or on two legs--without Evie's help. And when Evie reaches deep into the power of her magic to save her friend's humanity--and her prince's heart--she discovers, too late, what she's bargained away.
