Annie Colwater's only child has just left home for school abroad. On that same day, her husband of twenty years confesses that he's in love with a younger woman. Alone in the house that is no longer a home, Annie comes to the painful realization that for years she has been slowly disappearing. Lonely and afraid, she retreats to Mystic, the small Washington town where she grew up, hoping that there she can reclaim the woman she once was--the woman she is now desperate to become again.
