From the author of About a Boy and High Fidelity—and inspiring the Emmy winning series on Sundance TV—this slim novel is a witty, heartbreaking, and honest portrait of a marriage falling apart, and the lengths a couple would go to in order to fix it. Tom and Louise meet in a pub before their couple's therapy appointment. They'd always thought they had a stable home life, until a recent incident pushed them to the brink—but now, sharing drinks before their next meeting, they wonder if marriage, like a computer, is made of a million little pieces, and if you try to take it apart to see how it works, you may never get it back together again.
