After Toby Fleishman and his wife of 15 years separate, he expects weekends with the kids, some residual bitterness, the occasional moment of tension in their co-parenting negotiations. Instead, Rachel drops their two children off at his place and disappears, greatly complicating Toby's summer of sexual emancipation. Earning a National Book Award nomination and inspiring the 2022 FX on Hulu miniseries, Taffy Brodesser-Akner's debut follows Toby as he realizes that he has no path forward until he understands what happened to Rachel and what happened to his marriage.
