The Note by Alafair Burke (Paperback)

May has always been the good girl, the rule follower. But even good girls have secrets. When she reunites with her two best friends for a holiday in the Hamptons, a drunken joke lands the trio in the middle of a missing persons investigation. As the case takes a deadly turn, and long buried secrets are uncovered, the three friends are suddenly unsure who they can trust, least of all each other.
