One cold November night when Kat Kominski was fifteen years old, she and some friends held up a convenience store. In the heat of the moment, one of the others shot and killed an off-duty cop moonlighting as a security guard. Kat and her pals fled the scene in a panic, and no one was caught.Thirteen years later, Kat - now Kate White - has built a new life for herself. Now a single mom with a nine-year-old son, she works as a prosecutor in the Philadelphia DA�s office. But her dark past returns to haunt her when she walks into court one day and has a devastating encounter with a prisoner, Mario Castellanos, one of her companions from that terrible night.Hardcore criminal Mario is facing a possible sentence of twenty years. He lets Kate know that he is counting on her, his old friend turned prosecutor, to make sure he goes free instead. If Kate doesn�t do what he wants, he�ll claim she was the one who killed the off-duty cop.Kate is in a bind: If the truth about her past gets out, she stands to lose everything, including her son. But she can�t do what Mario wants, either. As Mario ups his demands, blackmailing and terrorizing her, she is forced to turn for protection to a sexy homicide detective, Tom Braga, who suspects her of�something. The two clash repeatedly as Tom keeps digging into her past, trying to learn the truth.Then another, far more menacing, threat rears its head, and Kate realizes that her life - and her son�s - are in terrible danger. Frantic, she sees that she has nowhere to turn. Except, maybe, to Tom�.
