Isabel Walker, a young, not-so-innocent, American abroad, arrives in Paris to find that her sister’s French husband (‘the frog prince’) has just walked out. While Isabel embarks on her own sentimental education -seduced by gourmet food, antiques, existentialism and an older man -her sister’s marriage disintegrates into bitter Franco-American wrangles over money, titles and a mysterious painting. With a sharp tongue and an ironic eye for the foibles of the Parisian bourgeoisie, the French art world and American ex-patriots, Isabel is a collector of experience, even those she can’t control.
