/lit/ - Literature

are there any atleast some-what contemporary (preferably fiction) books that picture the worst possible outcome for humanity?

best 89 iq example i can imagine: the world is thrown into a new dark age, u.s. is under constant civil war and is basically africa with nukes, education is non-existent and everyone relies on whatever little bits their parents can teach them, europe is completely controlled by tyrants and has a new genocide every weekend, indian and african phenotypes are the most common phenotypes you can find etc

any books along those lines? i wouldnt ask but i dont really know what to search for. idk if its retarded but i like to daydream about stuff like that lol.
