Past midnight, Chyna Shepherd, twenty-six, gazed out a moonlit window, unable to sleep on her first night in the Napa Valley home of her best friend's family. Instinct proves reliable. A murderous sociopath, Edgler Forman Vess, has entered the house, intent on killing everyone inside. Chyna is a survivor, toughened by a lifelong struggle for safety and self-respect. Now she will be tested as never before. At first her sole aim is to get out aliveuntil, by chance, she learns the identity of Vess's next intended victim, a faraway innocent only she can save. "Koontz's masterly pen once again builds the suspense to almost unbearable levels...Highly recommended." Library JournalPixel PlanetI found Intensity to be the best book that Koontz has written in quite some time. Great characters, great writing and a non-stop plot.
