In 1955, Grace Monroe's marriage has landed her at the heart of London's high society, but the role of sophisticated socialite doesn't come easily to her.

An unexpected inheritance from a French woman she has never met sends her on a journey to Paris, to a long-abandoned perfume shop where she discovers the bewitching story of Eva d'Orsey, a perfumer's muse in the 1920s. As Eva's past and Grace's future intersect, Grace realizes she must choose between the life she thinks she should live and the person she is truly meant to be.
