When the resurrectionists of Fissure's Whipp begin disappearing, eighteen-year-old Allie knows someone is after their blood—or, more accurately, the genetic mutation that allows their blood to heal wounds, save lives, and even bring back the recently deceased. Raised by her aunt after her parents' deaths, Allie knows staying vigilant means staying alive. She's trained her whole life to protect herself by any means necessary, from self-defense classes to extensive weapons training in knives. Now she’s gone so far as to befriend a homeless boy named Ploy who unknowingly trades a few nights a week on her couch in exchange for being a human tripwire to those hunting her. But as Allie and Ploy's feelings for each other grow, Allie realizes that, this time, she'll need more than fighting skills and a sharp blade to beat a villain literally out for blood. Protecting a girl he shouldn’t love from a threat he understands too well, Ploy must face his past to save his future in Allie’s world—a world where bringing back the dead can cost you your life.
