Anny Duperey

Imagine you fall in love with two men, and no matter what, however often you date one and then the other, or both, you can't make a choice. A threesome would be ideal, but socially not feasible. One of the men decides for you and leaves. Then, there's a party (une soiree) and rumours are "he" will be there. He is.
I loved reading this book. I can't compare it to modern French literature because I've hardly read any. But I will read more of Duperey's work.
