Denver homicide cop and shooting survivor Beck Stryker lives to solve the case that left him with PTSD, chronic pain, and killed his co-investigator four months previous. Now his career hinges on his ability to work with the man who shut down his advances two years ago. After last parting ways with Beck, psychiatrist-turned-FBI profiler Zach Littman never anticipated seeing the detective again. Being sent to Denver to work on a series of killings that have continued after the only suspect died is bad enough. Discovering the detective in charge is Beck leaves Zach gritting his teeth and girding his loins. The last thing either of them needs is romantic entanglement with a fellow investigator, but danger is a powerful aphrodisiac. The case heats up, and friction between them ignites a fire neither can ignore, first at work and then in the bedroom. As they zero in on the plot behind the murders, the crosshairs zero in on Beck and Zach.

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.
