Therapist June Graves moonlights as a killer who hunts abusive men. When a client's niece goes missing, all signs point to her dangerous ex-boyfriend, Theo Zervas. It doesn't take long for June to decide he will be her next victim.

Theo Zervas, president of a local outlaw motorcycle club, the Saints of Purgatory, is intimately familiar with danger and death. He's been looking over his shoulder his entire life, so it's not hard to notice his sexy shadow. When June attacks, Theo is ready for her. He gives her two options: sending the evidence he's gathered against her to the cops, or she lives with him as a Saint of Purgatory for one month. After, if she still wants to kill him, he won't stop her.

With no other choice, June agrees to the forced living arrangements. But neither one of them is ready for what the next month will bring. Theo's side job puts June in jeopardy, and June's murderous tendencies threaten to bring everything down around them. Now they have to make a decision: is staying in each other's lives worth it, or will this deal kill them both?

It doesn't take long before they realize they're more than a killer and a criminal. But is choosing each other worth the danger, or will this deal destroy everything?
