A self-proclaimed 'homicidal adventurer,' Vess lives only to satisfy all appetites as they arise, to immerse himself in sensation, to live without fear, remorse, or limits, to live with intensity.  When he gets Chyna Shepherd trapped in his deadly orbit he thinks she'll be easy prey, but Chyna is a survivor, toughened by a lifelong struggle for safety and self-respect . . .

Unfolding over the course of just twenty-four hours, Intensity is one of Dean Koontz's most inventive, emotionally intricate, and terrifyingly suspenseful works of terror.

“With tumbling and hallucinogenic prose Intensity rockets up the gloomy highway with the reader in violent pursuit.” -- The New York Times
