A Top 15 greatest science fiction books of all time.
I just don’t like the blatantly political books, 1984, Brave New World, Fahrenheit 451, Slaughterhouse 5. Not that they aren’t good books, just they’re barely science fiction.
If you want preach at people, do it like Battlefield Earth. 1 page of libertarianism and 999 pages of fighting aliens. I’m not saying Battlefield Earth is great literature, though it is an entertaining book, just that it has a good ratio of preaching to story.
