When sixteen year old Arella Cline's summer vacation begins with the tragic death of her parents, she is sent to live with her aunt to begin a new life on a remote island off the western coast of Ireland. But there are strange things happening on Tory Island-shadow figures, mysterious auras, and the haunting sound of her deceased parents' voices.

The only thing Arella finds appealing about Tory is the handsome, dark-haired Declan McQuillan. But Cannon Fidelous, a mysterious outcast, warns her that the island and its inhabitants are hiding a dark secret. And when Arella finds an ancient book of prophecies, she discovers the island's curse-a curse that only she can undo.
