Multifaceted author Blake Crouch writes horror, psychological suspense, science fiction, and thrillers, often overlapping several genres. Ghosts, murderers, and advanced technology drive the intricate plots while providing an endless source of white-knuckle tension and moral ambiguity. Offering a fast pace and plenty of drama, Crouch's work is creepy as it is atmospheric. (From Novelist)
