I had a difficult time getting through this one. Something about the writing style allowed my mind to wander quite a bit. I had to really focus on maintaining attention and honestly, while there are a lot of good observations in here, and some connections across novels that I wouldn't have picked up on my own, a lot of times it didn't seem worth the effort. If I was writing a thesis or something, I'd probably appreciate this more but I'm just reading for pleasure.
I would have abandoned it except that there will probably never be a time when I'll be in a better place to get something out of it, having just read all of Kundera's works. This was the last book having to do with Kundera that I had lined up, so it would have felt like quitting a marathon at the 26 mile marker. I had to finish it.
