Rise of the Saints - Vory v Vampyr, #1

Dragomir Saint is amassing an empire controlling black market trade routes through the Midwest, claiming his power with a singular brutality that makes him and his brothers a rising force to be reckoned with. When a hit sends him to the morgue, he finds he has a weakness after all, and it's not the GSW to the back of the head. It's the morgue attendant, one Cordelia Bloom. When he discovers she's being stalked by a killer the papers have dubbed "The American Ripper" he's determined to bring her the monster's head.
But when the autumn moon is full, a fiend who is dark of heart may become something more-something Dragomir never anticipated. He'll risk his kingdom, his brothers and his very life to save the one woman who reminds him of what it is to be human.
