Twelve people have been shot at point-blank range and left to rot in the desert sun. It’s Sophia St. Claire’s job to do something about it. She’s Bordertown, Arizona’s new chief of police - and she’s out of her depth. Help arrives in the form of Department 6 hired gun Roderick Guerrero. As far as Sophia’s concerned, his involvement only makes things worse. Maybe he’s managed to turn his life around. And maybe he’s a good investigator. But as the bastard son of a wealthy local rancher, he has a history he can’t get past. A history that includes her. Rod refuses to leave town until the killer is caught. He’s not worried about the danger posed by some vigilante. It’s Sophia who threatens him. Because he’s used to risking his life - but his heart is another story.
