It begins with a blackout. Cities everywhere come to a screeching halt as all electrical power slips from their grasps. And then their inhabitants begin to mysteriously vanish. All hope for recovery depends on two strangers: Dylan Barnes, a martial arts instructor cursed with demons who speak in tongues only he can hear, and Lucy Deverau, a private investigator haunted by the truth of her past. As the world around them fades to black, Lucy and Dylan find themselves in the front lines of an impossible battle against darkness.
