Detective Beck Stryker has a lot to juggle: his long-distance relationship with FBI profiler Zach Littman, the family issues of cop widow Marybeth Halliday and her two boys, and the ups and downs of being out and proud. To top it off, Beck must work with his closeted ex-lover Van on the case of a skeleton discovered in the woods. FBI profiler Dr. Zach Littman has been working on an exit strategy for months. Every time he’s on the brink of resigning, Minneapolis Unit Director Sands comes up with “one more case,” one that only Zach can manage. It’s a situation that frustrates Beck. Zach has promised he’ll leave the FBI and profiling behind—as soon as his Colorado medical license comes through. It may be easier said than done. Zach has reservations about uprooting his life and moving to Denver. A killer leaves a grisly invitation insisting Zach participate in a deadly game, the rules of which are known only to the psychopath. It’s clear taking out Zach is on the killer’s to-do list, and he won’t stop until it’s done. Beck and Zach must capture the killer before the psychopath finds Zach and declares Game Over.
