Name some. I can think of two off the top of my head.
Q, by Luther Blissett. It reads like a spy novel, real fun read, and it's all about peasant class conflict.
The Unseen, by Nanni Balestini. Set during social unrest in Italy the early 70s. A little arty (all the paragraphs are exactly the same length, punctuation is weird), really enjoyable none the less
Others?
Germinal, Zola
Devrim
