From the #1 New York Times bestselling author of the Elvis Cole and Joe Pike series comes a thrilling novel featuring LAPD K-9 Officer Scott James and his German shepherd, Maggie.

Nine months ago, a shocking assault by unidentified men killed Scott James' partner, Stephanie, nearly killed him, and left him enraged, ashamed, and ready to explode. He is unfit for duty—until he meets his new partner.

Maggie is not doing so well, either. A German shepherd who survived two tours in Afghanistan sniffing explosives before losing her handler, her PTSD is as bad as Scott’s.

They are each other’s last chance. And they’re about to investigate the one case no one wants them to touch: identifying the men who murdered Stephanie. But what they find could ultimately break them both.
