The book I'm readin now is Proust's In search of lost time.
I started first volume 5 years ago and had much difficulty in going through the book. Have read first 3 volumes, but didn't enjoy it much. As there is almost none of action and very, very long sentences which is hard to understand what idea author wants to express. On 4th book I've given up, but now after couple of years I returned to it and to my surprise I have a good time with it, so maybe I'll finish the rest.
