New York City's oldest and largest medical center is the scene of a ghastly attack: top neurosurgeon Gemma Dogen is found in her blood-soaked office, where she has been sexually assaulted, stabbed, and designated by the cops as a "likely to die." By the time Alex has plunged into the case, it's a high-profile, media-infested murder investigation with a growing list of suspects from among those who roam the hospital's labyrinthine halls. As Alex's passion to find the killer intensifies, she discovers this hospital is not a place of healing but of deadly peril - and that she is the next target for lethal violence.
