Query: Killing Britney: An enjoyable experience [spoiler warning]

Killing Britney is captivating. It goes beyond the cliched plot of a heroic preppy chick who is the heroine and person who solves the mystery. In fact, the preppy chick is the killer! Loaded with graphic scenes of carnage, imagination unnecessary, but still thrilling. The novel begins like Scream and ends like Hide and Seek.
