Fifteen years ago, the Rookie Club began as a tight-knit band of female cops struggling for respect. Jamie Vail was one of them. So was Natasha Devlin, the woman Jamie caught in bed with her husband.

When Natasha Devlin turns up dead, Jamie can't bring herself to care. She's got enough on her plate, hunting a sexual predator who preys on female officers. He leaves them alive, but brutalized. But when the MO of the Devlin murder matches the MO of the perp in Jamie's case, she's brought in on the homicide investigation and back into the Rookie Club she has been avoiding since her husband's affair.

As more cops become victims, Jamie must confront her past and solve the murder of her ex-husband's lover before she becomes the killer's ultimate prize.
