Raine Stockton and her high-spirited, big-hearted golden retriever Cisco are accustomed to being heroes wherever they go. But there’s a new dog in town, and Raine and Cisco find themselves unexpectedly upstaged by a flashy K-9 addition to the sheriff’s department. Nike and her handler, Jolene, are part of a new government-funded program for law-enforcement agencies, and though Raine admires Nike’s talent almost as much as she resents Jolene’s arrogance, she can’t help wondering why the Department of Homeland Security would send such an expensive gift to their sleepy little Smoky Mountain community.Sheriff Buck Lawson has his hands full with an upcoming election, a bizarre murder, and a special appearance by a celebrity politician at the Fourth of July parade, and he is not about to look a gift horse—or dog—in the mouth.
