Obviously I recommend Hoellebecq's novels, mainly "Atomised", "Whatever" (very blackpilled novel where we met the incel character Tisserand) and "Submission" (where we can see how liberal and secularized France submit herself to Sharia also because sexually frustrated men can achieve one or more wives in this way).
I advice also very interesting dystopian novels like Orwell's ones ("1984" and "Animal farm") and above all "Brave New World" by Huxley, where we can see a very likely future society, where sexuality is polygamous and moral-free since childhood and humanity is divided into classes based on beauty and intelligence both scientifically determined (obviously top classes are beautiful and intelligent and selected for high-level jobs, while lower ones are at the bottom of the society).
Then, some of my favorite books are all Tolkien's and Asimov's works, the best choices if you like respectively fantasy and/or sci-fi.
About politics, I can suggest a lot of stuff both on Fascist/NatSoc and Socialist/Communist sides, but about contemporary writers I recommend the (relatively mainstream, at least here) hegelo-marxist Italian philosopher Diego Fusaro, one of the few who condemn the today promiscuous sexuality from the left.
I would be really glad to read some book advices by @IntolerantSocialist however!
