How well does Quinn know Esther, the roommate who has mysteriously disappeared from their Chicago apartment? Is Esther the young woman who shows up suddenly in Alex’s small Michigan town on the lake and, if so, why is she there? Quinn and Alex tell their own stories in alternating chapters and the reader has no reason not to believe them and yet… there are elements in both of their personalities that could lead them to misinterpret events. Mary Kubica’s well-plotted story creates page-turning tension without cheating, resulting in a suspenseful tale with an unpredictable but utterly believable resolution. Highly recommended.
