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'll 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: he sends 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?
