About the book: 2008 / One cold November night, fifteen-year-old Kat White and her friends were walking to a convenience store. In the heat of the moment, one of them shot and killed a retired policeman who worked as a night security guard. Kat and her friends fled in panic, but no one was caught. Sixteen years later, Kat - now Kate - has built a new life for herself. A single mother with an eight-year-old son, she works as a prosecutor in a Philadelphia court. But the dark past returns when one day she comes to court and learns that she must accuse Mario Castellanos, one of those who were in the company that night. Kate is backed into a corner: although Iario probably committed the crime, he blackmails Kate, wanting to make sure he is not convicted. Otherwise, he promises to reveal that she was one of those who killed the cop. Before despair could overwhelm her, Mario was found dead - killed in her apartment and with her gun. When homicide detective Tom Braga begins the investigation, things don't get easier for Kate: they met when she first started working as a prosecutor. But when another person who knows about Kate's past interferes with the investigation, she realizes that her and her son's lives are in danger. She feverishly realizes that she has nowhere to wait for help. Except maybe Tom...
