Back with the FBI, Sinclair "Sin" O'Malley has promised that this time she'll play by the rules. After a body is discovered lying on the sands of Miami Beach, she's called in to lead the investigation. As the body count begins to rise, Sin soon realizes that she must dissect the killer's MO by entering into a dark, twisted mind. Sin must go head to head with a madman whose artistic vision is clouded by a nightmarish past. A killer who lives by the belief that, "Nothing gets in the way of the art." Pieces of the horrific puzzle link back to her friend, Charlie, and a case he solved forty-three years earlier. As confusion muddles her confidence, Sin must remind herself of the person she truly is: A righter of wrongs, an advocate for the underdog . . . the Pearl Angel of Death. When dealing with madness, one needs to be mad. Laws must be set aside. "Rules were made to be broken."
