Fairfield Detective Alexis (Alex) Martinez is in pursuit of a killer so brutal, he holds an entire city in the grip of terror. His victims are picked at random; their torture and mutilation, unspeakable. As the body count rises, Alex's investigation puts her among the hunted-not by the serial, but by a much greater threat: a secret society with members imbedded inside world governments, law enforcement and every walk of life. Their prime objective is to avert discovery, and when her investigation comes too close to revealing their existence, Alex becomes a target. The only one that can save her is the trained assassin they've sent to kill her; someone who has already infiltrated her heart and mind, and who may be the monster she's been chasing all along.
David Jason Sawyer is a predator with the face of an angel, his mind a weapon as equally formidable as his body, prince of a powerful hidden society believed to represent the next step in man's evolution: Family. Their physiology has evolved to consume bio-energy directly. They're stronger. They age at an incredibly decelerated rate. With their extraordinary ability to heal, they're close to invincible. And they feed on humans to survive.
Since childhood, Sawyer has been trained to manipulate and entrap on reflex, to put emotion second and Family first; yet one moment of weakness, sparing the very detective that hunts him, the woman he has grown to love, makes him a dangerous threat his people cannot tolerate.
Now, light must join forces with darkness as Alex and David struggle to stay one step ahead of an invisible army out to silence them both.
