The old world burned the night Justin was forced to slaughter his own family.
Now, the streets of Denver have devolved into a primeval hunting ground. A virulent outbreak has stripped humanity of its sanity, leaving behind ravenous, bloodthirsty stalkers that devour everything in their path.
Justin is surviving, but the isolation and the relentless brutality of the new world are taking their toll. He can feel a dark, merciless instinct waking up inside him-a thirst for blood that rivals the monsters he's fighting. But when a chance encounter reveals that the infection is no accident, Justin finally has a reason to keep moving.
His destination: a medical lab in Chicago that might hold the cure. But with a shadowy syndicate hunting him down and humanity turning on itself, the stalkers might be the least of his worries. To find the truth, Justin will have to embrace the monster within.
