High in the hills above Albuquerque, New Mexico Detective Zachariah Ellison arrives at the scene of a murder, and not just any murder, but one that definitely falls into the 'gruesome' category even for a seasoned cop like Zach. When another body is found murdered in much the same fashion, Zach knows he's got a serial killer on his hands, and to top it off he's got an assistant district attorney hounding him about the case. As Zach tries to investigate the crimes while sidestepping nosey Amy Logan, a third body is found and Zach hasn't a clue as to whom the perpetrator might be. Amy Logan has worked hard to put herself through school and pay for law school on her own and now that she's secured a position as assistant district attorney in Albuquerque, she's determined to do everything she can to be the best prosecutor this office has ever seen. And as if luck was following her, she's been assigned to the biggest homicide case the city has ever seen. The only problem she's having is the homicide detective who's leading the investigation-Zach Ellison.
