Sarah Price has never regretted trading her MFA for a steady job so that her husband, Nathan, could write fiction. But at age 35, her world is turned upside-down by a shocking revelation: Nathan's upcoming novel, Infidelity, is based on fact. Reeling from his betrayal, Sarah is plagued by dark questions. How well does she really know her husband? More important, how well does she know herself?

For answers, Sarah looks back to her artistic twentysomething self to try to understand what exactly has happened to her dreams. And so begins her quest to discover which version of herself is the essential one --- the artist, wife, mother, or someone else entirely --- an eye-opening journey that leads Sarah hundreds of miles away from her marriage and back to herself.
