London, 1955: Grace Monroe is a fortunate young woman. Despite her sheltered upbringing in Oxford, her recent marriage has thrust her into the heart of London's most refined and ambitious social circles. However, playing the role of the sophisticated socialite her husband would like her to be doesn't come easily to her --- and perhaps never will.

Then one evening a letter arrives from France that will change everything. Grace has received an inheritance from a mysterious benefactor, Eva d'Orsey, whom she's never met.

So begins a search that takes Grace to a long-abandoned perfume shop on Paris's Left Bank, where she discovers the seductive world of perfumers and their muses, and a surprising love story. Told by invoking the three distinctive perfumes she inspired, Eva d'Orsey's story weaves through the decades, from 1920s New York to Monte Carlo, Paris and London.

But these three perfumes hold secrets. And as Eva's past and Grace's future intersect, Grace must choose between the life she thinks she should live and the person she is truly meant to be.
