1938: She was one of the six sparkling Mitford sisters, known for her stinging quips, stylish dress, and bright green eyes. But Nancy Mitford's seemingly sparkling life was really one of turmoil: with a perpetually unfaithful and broke husband, two Nazi sympathizer sisters, and her hopes of motherhood dashed forever. With war imminent, Nancy finds respite by taking a job at the Heywood Hill Bookshop in Mayfair, hoping to make ends meet, and discovers a new life. Present Day: When book curator Lucy St. Clair lands a gig working at Heywood Hill she can't get on the plane fast enough. Not only can she start the healing process from the loss of her mother, it's a dream come true to set foot in the legendary store. Doubly exciting: she brings with her a first edition of Nancy's work, one with a somewhat mysterious inscription from the author. Soon, she discovers her life and Nancy's are intertwined, and it all comes back to the little London bookshop--a place that changes the lives of two women from different eras in the most surprising ways.
