Ashling Donoghue is no closer to finding her parents than she was the night they disappeared. But hope returns as her brother Kian channels the Sword of Light, revealing past-life secrets and truths long suppressed. The more she learns, the greater she fears the darkness that drowns the Netherworld also drives her. Is Aengus her true love, or is it Lorcan? Does her future wait in shadow or the light? One point is clear: the threads of her past-self are woven inextricably into the tapestry of her soul. An impossible choice looms before her, and all the while, evil is poised to strike.
