Everywhere Detective Gavin DeGrassi looks he’s reminded of his attack by the Breath Play Killer. It’s in the house he lives in with his partner and Dom, Ben Haverson. It’s in the sympathetic yet pitying looks he receives from his fellow detectives when he returns to the force after a year-long hiatus. It’s in the suffocating coddling of his entire family, and the relentless reporter demanding an exclusive of his ordeal. Most of all, it’s in his lack of submission to Ben, who isn’t convinced Gavin’s recovered enough to trust the power exchange between them. The miraculous recovery of two teen boys from a twisted kidnapper gives him heart, and Gavin's determined to prove he can handle anything despite increasing strain between him and Ben, painful nightmares, and panic when anyone touches him. But his next case is too close for comfort: a friend and colleague found raped and murdered in a fate chillingly similar to what could have been his own, and this killer isn’t stopping with one cop. As the body count rises and taunting souvenirs are being hand-delivered to Gavin, he faces a frustrating lack of leads, a crushing need to prove himself, and a sinking suspicion the imprisoned kidnapper’s reach is further than originally thought. A miasma of uncertainty and fear threaten to suffocate him when he asks a question with which he’s overwhelmingly familiar: what happens when a victim is pushed too far?
