Kill switch
(Books)

Brilliantly constructed and breathtakingly suspenseful, this novel is a masterful combination of murder, mystery, and modern forensics that will keep you hooked until the final shocking conclusion. Dr. Claire Waters understands what motivates violent criminals, and she tries to prevent them from committing further crimes. Haunted by a childhood brush with a vicious crime that was never solved--the abduction of her best friend--she must confront her own worst fears when she takes on her first serial killer case. She meets with Todd Quimby in the bowels of Rikers Island prison and sets out to crack his tough exterior, but she overlooks his violent nature and recommends his release. Within twenty-four hours, Claire is horrified to realize that the body of a murdered woman in Times Square bears all the hallmarks of a Quimby victim. Soon the killer taunts her, her supervisors doubt her, the cops resent her, and her boyfriend questions her loyalty. Determined and daring, Claire agrees to be a decoy. Risking everything, she uncovers a devious medical conspiracy that threatens to disrupt the international balance of power. She must confront both a killer and a conspiracy--or die trying.
