From No. 1 New York Times and USA Today bestselling author P. C. Cast, a passionate and magical epic bringing alive Celtic legend

Step into the mystical world of the Isle of Skye, where legends come to life, goddess and gods walk the mortal earth, and the Queen of Shadow holds court. But Scáthach is no ordinary queen.

Scáthach dedicates her life to training the most talented warriors from across the ancient world. When Cuchulainn, the Hero of Ulster, arrives asking to become one of her students, Scáthach reluctantly agrees to train him, despite her misgivings about his past. Scáthach soon realises Cuchulainn is much more than the brutal warrior everyone expects him to be. And the Hero of Ulster begins to believe he might take control of and even change his foretold fate.

As their attraction deepens, Cuchulainn's father, the God of Light, forces him to retrieve a weapon that will seal his fate and forever take him away from the Queen of Shadow. But, when Scáthach joins him on his quest, she will discover that she might be able to forge a future for herself and Cuchulainn by tricking death herself....
