American doctor Tara Moore wants to disappear. On the run from an abusive husband, she seeks shelter on a windswept Irish island and dismisses the villagers' speculation that she is descended from a selkie-a magical creature who is bewitching the island. But when a ghostly woman appears to her with a warning, Tara realizes it was more than chance that brought her to this island. Desperate to escape a dark and dangerous past, she struggles against a passionate attraction to handsome islander, Dominic O'Sullivan. But the enchantment of the island soon overpowers her and she falls helpless under its spell. Caught between magic and reality, Tara must find a way to wield both when a dangerous stranger from her past arrives, threatening to destroy the lives of everyone on the island.
