From The New York Times and USA Today best-selling fantasy author Richard A. Knaak comes a vivid new adaptation of the legend of the great Celtic hero — Cuchulainn, the Hound. Born of one of the mystical Tuatha de Dannan and a stolen human princess, then fleeing from their supernatural island domain while still a youth, Cuchulainn must strive to survive and claim his kingdom in a world where both powerful mortal and magical foes will use force and deceit to bring him down. Yet, even more deadly to Cuchulainn than any sword or spell and the one enemy that he may not be strong enough to overcome is the raging beast within him . . . a beast that may also mean doom to all he holds dear.
