Carolyn Keene

Nancy Drew is seventeen and good at everything...ESPECIALLY solving crimes. But her totally-in-control-and-obviously-running-perfectly-smooth-(but-not-really) life hits a snag when a mysterious message drags her back to the hometown she left behind. There she'll have to find out which of her friends are still her friends, which are enemies, and who exactly is trying to kill her...and (hopefully) stop them before they succeed. --from Amazon.
