Consider Phlebas by Iain M. Banks (1987) The late Iain M. Banks great contribution to science fiction was a series of books about the Culture, a sprawling, semi-utopian society where work and scarcity have been largely eliminated and advanced artificial intelligences pull strings behind the scenes. Larry Niven is one of the greats of engineering SF, and Ringworld is probably his best-known work — it won the Hugo, Locus, and Nebula awards, and its titular ringworld has become a fixture of science fiction. The Left Hand of Darkness by Ursula K. Le Guin (1969)
