Ten years ago， I was seventeen， spending summers with my wealthy family and friends on Hawk Island。 One terrible night， I blacked out。 The next morning， my best friend Melanie was gone—vanished without a trace。

Ten years ago， my life changed forever。

Today， I have to go back…

To my sister's wedding， to a group of wealthy privileged people with whom I've never belonged。 To my best friend's brother， who hates me and the world I come from。。。and who blames us all for his sister's disappearance。

When an unexpected summer storm hits the island， we're trapped—and another woman goes missing。

Is history repeating itself？ Is there a killer among us？

Will I be the next one to disappear？
