After attending a disastrous social gathering, drinking too much and fighting with her husband, Dani Keller wakes up alone and confused, but not yet worried. Worry slowly settles upon her as the hours pass, the day draws to a close and Dani realizes that her husband has vanished, and she cannot remember exactly what happened the night before. While the story does get bogged down in the middle with too much relationship analysis, and despite the fact that Caletti seems to be trying a little too hard to write this year's Gone Girl, this is a solid suspense story.
