Milan Kundera: one of my favourite (although previously despised) authors.
I personally enjoyed 'Ignorace' much better than this book. I'm not sure if I was paying enough attention to it when I read it this morning, but his philosophies and theories about identity didn't seem to hit me as hard as the nostalgia of 'Ignorance'.
This novel revolves around the lives of a Parisian couple: Jean-Marc and Chantal. The narrator is strictly third-person but his perspective reclines on either couple alternately.
The ending isn't so sad.
