North Carolina native Raine Stockton, a dog trainer and the ex-wife of a deputy sheriff, knows the woods of Hanover County as well as anyone. She stopped volunteering for Search and Rescue work after a tragic loss, but now she reluctantly returns to active duty-along with a young and inexperienced Golden Retriever named Cisco-to help find a mother and six-year-old girl who have been kidnapped and taken deep into the wilderness. Suspecting there's more to the case than meets the eye, Raine must struggle to overcome her personal demons, turn her search in new directions-and learn to trust Cisco to lead the way.
