Visited by tragedy and heart-wrenching deception, Erin retreats into self-imposed isolation. But the Fates are not finished with her and she is uprooted from her respite to face the dark forces that threaten to swallow her entirely. Aidan, fettered by his dark parentage and past, is drawn to Erin by the duties of his position and is held to her by the love she awakens in him. Bradach is powerful, beautiful, immortal and ever struggles with his all-too-human jealousy. Erin can't understand his hatred for Aidan, nor can she shake the feeling that she has known him from some other time, but the feeling is fleeting and can't be held to grasp. Brieanna, Erin's life-long friend, wears wisdom like a comfortable old shawl, and her quiet confidence is just what Finn, Aidan's brother, needs to escape the terrors that drive him. The four humans find themselves the central figures in a centuries-old prophecy and bind themselves together to fight the encroaching horrors from the south that threaten to cover the four kingdoms of Tara in shadow. Tara must now return to the magic that was such a rich part of their heritage, now reviled, in order to save the lands they love. Standing together with the four immortal Elders of Tara; Erin, Aidan, Brieanna and Finn take their predestined places as the Bearers of the Promise and the saviors of Tara.
