In the post-apocalyptic Midwest, now a ravaged dust bowl, former guardsman Derek Covington must find help for a sick boy. With nothing but memories of all he lost, Derek crosses the desert alone in search of the doctor who saved his own life ten years ago. Drifter gangs who loot and pillage don't dare come near, for Derek has a formidable weapon: a prosthetic arm with a deadly blade.
For a decade, Dr. Lidia Sullivan has fantasized about the handsome guardsman who'd been in her care. And now she can't deny his dangerous request. But as they make the treacherous journey back to Old St. Louis, they must contend with much more than fierce desert winds and their unthinkable attraction. A fearless gang has spotted Lidia—a rare woman—and will fight Derek to the death to get her. And though he risks his life to save her for the sake of the child who needs her, she fears there's one thing Derek will never risk: his heart.
