<b>Man's best friend goes to war.</b> <p>When Gus Dempsey joins the US Marine Corps, he knows without a doubt that he will make a great dog handler. He's always been good with dogs. In fact, he's often better with dogs than he is with people.</p> <p>But Loki is not the dog that Gus was expecting. Fun-loving and playful, Loki acts more like a pet than the well-trained, bomb-sniffing Marine that he's supposed to be.</p> <p>When Gus and Loki deploy to Afghanistan, though, they have no choice but to learn to work together. Because in war, getting along is a matter of life and death.</p>
