A book that might be featured is 'A Canticle for Leibowitz' by Walter M. Miller Jr. It's set in a post - apocalyptic world where the Catholic Church preserves knowledge. Another could be 'The Left Hand of Darkness' by Ursula K. Le Guin, which explores gender and society in a unique way. And 'Ringworld' by Larry Niven is also a possibility. It has a fascinating concept of a huge, artificial ring - shaped world.
