With his surgery postponed, Harper can finally take on a War Dog case to help out Kat and Badger. Harper knows it is short-term, a fill-his-time thing. Considering his stage of life, that is perfect. Finding out he needs to find two dogs is a surprise, but he doesn't expect to track one dog in order to keep another alive.
As Saffron works to keep Beast alive, she knows how important it is to find Beauty, his bonded partner. The pair of War Dogs had come to Saffron for medical treatment. Beauty had thereafter been released, supposedly taken to a huge training facility in Mississippi, while Beast hadn't been healthy enough to leave Saffron's care. With Beauty missing, finding Harper on Beauty's trail is both a relief and a distraction. Saffron can't ignore the dynamic Harper, even as injured and as scarred as he is. Not to mention the work he's doing is so close to her own.
As Harper gets closer to Beauty's location, it becomes obvious that someone wants to make sure the War Dog doesn't reach her destination. But why? And how far will this person go to take down the dog?
