On the morning of their fifth wedding anniversary, Nick's wife, Amy, has disappeared. Nick is weak, Nick is a liar, and maybe he's not the very best of husbands — but is he a killer? Amy's diary reveals turmoil over their marriage, strange sicknesses, and her deep wish to be a mother — but is she telling the whole story? As the evidence slowly mounts, and the police investigation deepens, Nick is incriminated in horrible ways. He swears he didn't murder his beautiful wife and goes on the offensive to clear his name. The mystery of Amy's disappearance only gets more tangled as secrets unfurl from the web of their knotty marriage, and it becomes clear that something may have happened more disturbing than death.
