Cressida Mayfield, a troubled, immature 19-year-old college student, goes missing from the small city of Carthage, New York. Brett Kincaid, a badly injured, decorated Iraq war veteran who was previously engaged to Cressida's sister Juliet, is suspected of being involved in the disappearance.
Cressida's parents, Zeno and Arlette, are shattered by the tragedy as is Brett's embittered, neurotic mother, who accuses all and sundry of wronging her "war hero" son. We find out about the lives of these characters, what happened to Cressida, and the devastating consequences of her disappearance.
Can't say too much more without giving away spoilers so I'll just say the story points out how much we may not know about people close to us. Good book, worth reading.
