But Dexter's happy existence is turned upside down when he is called to an unusually disturbing crime scene at the university campus. Dexter's Dark Passenger – mastermind of his homicidal prowess – immediately senses something chillingly recognizable and goes into hiding. Dexter is alone for the first time in his life, and he realizes he's being hunted by a truly sinister adversary. Meanwhile he's planning a wedding and trying to learn how to be a stepfather to his fiancé's two kids – who might just have dark tendencies themselves. Macabre, ironic, and wonderfully entertaining, Dexter in the Dark goes deeper into the psyche of one of the freshest protagonists in recent fiction.
