"Emily Hunt went missing from her affluent liberal arts school on graduation weekend. Her body was found floating in a river, and a quiet loner who most people on campus really didn't know died by suicide. A tenuous link--one text--bound the two dead students together and was enough for law enforcement to close the case. ... Twelve years later, college friends gather to celebrate an engagement over a long overdue getaway on a swanky private island in Maine--with only one way in and one way out. Sierra Prescott, invited as a guest and unconnected to past events, is the only person who soon senses not all is what it seems"--Publisher description.
