France, 1714. A desperate woman makes a desperate deal in the dark - a bargain to live forever but be remembered by none. So begins the invisible life of Addie LaRue, shadow muse to artists throughout history, forgotten friend, confidante and lover, slipping away with the morning light. Addie passes through lives, desperate only to leave a trace of herself. Until the day she walks back into a small bookshop in Manhattan and meets Henry, who remembers her. After 300 years Addie's life is restarting, but the devil never plays fair. As Henry and Addie's lives start to intertwine, they must face the consequences of the decisions they've made and the prices to be paid.
