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.
