Under a thick canopy of pine trees, Cassidy Wilder frantically searches for a hiding place. Her breath catches in her mouth as she hears heavy footsteps. She says a silent prayer, but she knows he's closing in on her. She knows it's too late…

When a robbery at a local store ends with multiple deaths and the abduction of sixteen-year-old schoolgirl Cassidy Wilder, FBI agent Beth Katz and her partner Dax Styles are called in. Visiting Cassidy's family home just a couple of blocks away from the quiet little store where she went missing, Beth's heart breaks as she talks to her grieving parents and promises to find their daughter.

Looking at CCTV footage, Beth is horrified to see how calm the killer is as he shoots everyone in the store before forcing the terrified Cassidy to follow him into his truck. Then Beth uncovers multiple robberies just like this one, where all witnesses are killed and a young girl is taken. All of the victims are taken at night and found dead the following morning, so Beth knows time is running out to save Cassidy.

When Cassidy's lifeless body is discovered dumped on a busy highway near a patch of forest, Beth is devastated. And as more girls go missing, she fears the murderer is escalating. A breakthrough finally comes when she finds a name written in blood next to one of the bodies. Beth knows she's close to catching the killer and is determined to stop any more lives from being taken-even if it means serving her own form of justice. Will she be able to resist the urge to take a life herself? Or will she become the killer's next victim?

Perfect for fans of Robert Dugoni, Lisa Regan and Melinda Leigh, this absolutely nail-biting new crime series from USA Today and Wall Street Journal bestselling author, D.K. Hood, is sure to keep you up all night!
