Ashling Donoghue never dreamed moving to Ireland would rock her perception of reality and plunge her into a mystery that brings legend to life. At seventeen, she’s never had a boyfriend, but she feels an immediate connection to Aengus Breasal, the son of the wealthy Irishman who’s invited her family to stay at his Killarney estate. For the first time in her life, a guy she likes seems attracted to her. But Aengus is secretive, with good reason. He and his family are the Tuatha Dé Danann, ageless, mythical guardians adept at shifting between this reality and the magical dimension known as the Otherworld. Evil forces from that world threaten the Breasals, the Donoghues, and all of Ireland. Ashling must open her heart, face her fears, and embrace a destiny greater than she could ever have imagined.
