Worlds collide as Kirstie Blake and Marauder Dr. Niam Maraigh meet as he hunts down a rabid rapist. After saving Kirstie from the man's attempted attack, Niam vanishes, his body and soul afire with thoughts of the young consultant. Yet, the hand of Morrigu hasn't finished with these two as Kirstie's best friend is beaten and raped, forcing Kirstie to seek the services of psychotherapist, Dr. Maraigh. When they meet once again under these circumstances, they sense they are kindred spirit.

Bent on bringing the attacker to justice, Kirstie seeks to find this rapist before he finds another victim. For Niam, the only way he can help ease the pain of his patients, almost all exclusively emotional and physical trauma victims, is to take vengeance in their behalf. When he rescues Kirstie from one of the storm and war god, Taranis' minions, Niam is forced to reveal his true nature to the woman as both an ancient Druid and an energy vampire.
