This bestselling and innovative debut novel from Audrey Niffenegger explores an ideal marriage, one which is tested by challenges the couple can neither control nor predict. An imaginative expansion of everyday lifestyle, the storyplot asks: What if two different people who liked one another deeply, married, and experienced a life where one person remained constant as the additional slipped fluidly in and out of your time?

A modern love story having a twist that invites us to linger over queries of how life and love switch over time.
