A New York Times Bestseller Longlisted for The National Book AwardToby Fleishman thought he knew what to expect when he and his wife of almost fifteen years separated: weekends and every other holiday with the kids and the occasional moment of tension in their co-parenting negotiations. He could not have predicted that one day, Rachel would just drop their two children off at his place and simply not return. As Toby tries to figure out where Rachel went, his tidy narrative of the spurned husband is his sole consolation. But if Toby ever wants to truly understand what happened to Rachel and what happened to his marriage, he is going to have to consider that he might not have seen things all that clearly in the first place.
