On sale December 13, 2011, Kill Switch is the first in a series of high-concept suspense novels by Neal Baer and Jonathan Greene, the producers behind the hit television dramas "Law & Order: SVU," "ER" and the new CBS show, "A Gifted Man."

With her unnervingly personal insights into the criminal mind, Claire is drawn to the rare "untreatable" patients who seem to have no conscience or fear. She believes that by understanding what motivates violent criminals, she can help prevent them from committing further crimes.
