For Sarah, everything is in the middle: her life, her career, and her recently repaired marriage. And in this "taut, tense story" (NYTBR), despite the years that have passed since she last saw her daughter, she is still very much in the middle of figuring out what happened to Leda, and how she will let that loss affect the rest of her life. After her phone is stolen—losing her any last connection to Leda—Sarah and her husband receive an invitation for a weekend in the country with old friends and their new, unexpected baby. Over the course of three hot September days, the two couples try to reconnect, forcing Sarah to confront the truth about herself.
