One night Lauren finds a strange man in her flat who claims to be her husband. All the evidence – from photos to electricity bills – suggests he’s right. And then another one appears.

Lauren’s attic, she slowly realises, is creating an endless supply of husbands for her. There’s:The one who’s too hot (there must be a catch). The one who pretends to play music on her toes.

The one who can calm her unruly thoughts with a single touch. But when you can change husbands as easily as changing a lightbulb, how do you know whether the one you have now is the good-enough one, or the wrong one, or the best one? And how long should you keep trying to find out?
