In my bookclub we read a mix of classics and modern literature. Some of the best 'classics' for my groups over the years have been:

Lolita (1 month) Nabokov
East of Eden (2 months) Steinbeck
Anna Karenina (2 months) Tolstoy
Knight of the Maison Rouge (1 month) Dumas

I could go on, but those four really got our group talking and also showed us great differences of opinion. I lead an all female bookclub, and half of us are school teachers as well. I would love to see my group do M. Bovary....maybe next year!
