Widowed just two days after her marriage to a man twice her age, Marnie finds herself an outsider in the remote seaside village of Torcurra. Spurned by the townsfolk who suspect her involvement in her husband's death, she has only two friends: the local priest and the madman known as Raver, who is even more of an outcast than Marnie.

Marnie makes a remarkable discovery about Raver, whom she renames Raven, and the two forge a deep bond that begins to heal her own bruised heart. But the suspicious villagers see Raven's transformation as evidence of witchcraft, and suddenly Marnie finds herself facing an ordeal that threatens not only her future with Raven, but her very life.
