A quiet little town in upstate New York, Lake Charlotte is the perfect place to raise a family. Or is it? People still talk about that summer ten years ago when four teenage girls mysteriously disappeared. No one remembers that summer more vividly than Rory Connelly. Her older sister Carleen vanished from her bed in the middle of the night, never to be seen again. The fear and uncertainly of Carleen's fate destroyed Rory's family and her only escape was college. When she left Lake Charlotte, she vowed never to return. But now, ten years later, Rory Connelly is coming home.

It's only supposed to be for the summer while her brother's away. Until then, Rory has to cope with her mothers slow descent into insanity and her rebellious teenage sister Molly. The arrival of Barrett Mailtand only makes things worse. The handsome stranger knows too much about the past and is constantly asking Rory questions.

Then, on the anniversary of the very first disappearance, another teenage girl vanishes. Once again, Lake Charlotte is gripped in fear, and for Rory, it's the past nightmare revisited. Only this time, her own life is in jeopardy.
