An elite brotherhood stands between humans and vampires, preventing one side from annihilating the other. Who are called to this service? Only those warriors who curse God with their dying breath. Welsh warrior Peredur falls to a spear before he can claim Tanwen for his bride. Raging on the battlefield, Peredur utters the curse that seals his fate and leads him to another life. Using the power of a saint whose bone makes up an amulet, Peredur takes on the trials to become a true member of the brethren. Yet his need for the chieftain’s daughter Tanwen still burns. Tanwen resists her father’s command to take a husband. The only one who understands her sorrow is Cavan, the wise woman’s son. When he promises that he can reunite her with her beloved, she agrees to his terms. But does Tanwen truly understand the depth of the price that must be paid?
