'Not just a master of our darkest dreams but also a literary juggler' - The Times

If you delight in the suspense of Stephen King and Harlan Coben, you'll love Intensity - a classic thriller by Sunday Times and New York Times bestselling author Dean Koontz.

Edgler Vess is a sociopath intent on murder. He lives for one purpose only: to satisfy all appetites as they arise, seeking ever more outrageous experience. To live with intensity.

When he attacks her friend, Laura, Chyna Shepherd is saved by the instincts developed during a dark and turbulent childhood. Not knowing Laura is already dead, Chyna follows, hoping to save her friend, as Vess carries her body to his motor home - a dungeon and morgue on wheels. The killer, unaware of her presence, drives away. But Chyna is now trapped in his dangerous orbit.

Her sole aim is to get out alive, but when she learns the identity of the killer's next intended victim, she knows she must act to save that precious life - and take risks beyond any that she ever imagined she could endure.
