Detective Liz Boyle knows there is no crime more heinous than the murder of a child. When she and her partner, Tom Goran, are called to a new scene in an area of Cleveland known as The Flats, they find that a killer has taken that to new levels. As the investigation takes them deeper into the city's seedy underbelly, the case hits frighteningly close to home when someone Liz loves is added to the list of possible suspects. While fighting her personal demons, she must also pick her way around the department bureaucracy to avoid being pulled from the case. Liz and Tom will need to solve the most mind-bending mystery of their careers, one in which their personal and professional allegiances-and maybe their sanity-will be tested. But Liz vows to bring the killer to justice at any cost.
