Detective AJ Parker left undercover work in Atlanta to join a small-town Tennessee police force, hoping for an easier workload and the solitude of his cabin. But the scars left by AJ's previous work are more difficult to escape than he thought ... Mary Hannah Gallo works with the Second Chance Ranch Animal Rescue to train therapy dogs for traumatized patients. It isn't easy, but her life is under control—until she meets the broodingly sensual AJ, who rattles her composure all the way to her toes. After an assignment confiscating dogs from a backyard breeder reveals a dangerous drug operation, AJ must work with sexy perfectionist Mary Hannah to train an abused rescue dog—a dog now named Holly. While Holly proves to these two very different people that opposites can, in fact, attract, she also knows more than a few explosive secrets that could heal—or divide—the entire town.
