I am looking for some thought-provoking sci-fi or fantasy that can generate fun discussion. It can be modern or classic. Not looking for horror. No sexual content. Less than 200 pages. By thought-provoking, I do not mean just an engaging story. I mean a story that explores ideas.
I have already read lots of Isaac Asimov, and so leave him out. I enjoyed his work, but I want something different.
