It's August in New York, and the only thing that's hotter than the pavement is Manhattan D.A. Alex Cooper's professional and personal life. Just as she's claiming an especially gratifying victory in a rape case, she gets the call: the body of a young woman has been found in an abandoned building. The brutality of the murder is disturbing enough, but when a second body, beaten and disposed of in exactly same manner, is found off the Belt Parkway, the city's top brass want the killer found fast.
Success can never be guaranteed in every case Alexandra Cooper prosecutes, but for once the odds are with her; she is able to put away a serial rapist for a crime he committed over twenty years previously. But outside the courtroom another predator is at large.
The bodies of seven women have been discovered in Skull Valley, Arizona. Jonah Young, a private security operative from Department six, has been hired by the Yavapai County sheriff to assist in solving these murders. But Jonah’s not prepared for the complications that arise when he’s forced to work with a woman from his past, private investigator Francesca Moretti. Jonah betrayed Francesca 10 years ago. She hasn’t forgiven him and she’s pretty sure she never will. But the woman she was hired to find has been murdered in exactly the same way as the seven in Skull Valley, so, Francesca has to work with Jonah.
