Amelie is thirty years old, the haute-bourgeoise wife of a distant husband and model mother of two picture-perfect daughters.

One evening in a service station on the outskirts of the Bois de Boulogne, David drives into her life. Twenty years her senior, darkly handsome and almost embarrassingly virile, he is a suave filmmaker, a confirmed bachelor, and the perfect match for the perfect affair – but one with a twist. Anything but the conventional lonely wife, Amelie is capricious, snobbish, and sometimes deceitful. She brings to the affair the same fastidious care and controlled affection that she brings to her choice of hats. Just what David thought he had in mind – until he falls in love with her.
