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.  Today, I go back. To the island. To my sister’s wedding. To a group of privileged people with whom I’ve never belonged. To my best friend’s brother, a man who hates us all. To secrets that someone will kill to keep.
