Great taste anon. I've read all Houellebecq and I think it's his best, with Extension du domaine de la lutte (Whatever I think in english), more raw about alienation. A lot of Houellebecq's characters are reactionnary or straight up incels, but that's just for the sake of being edgy. They are blatant reflections of who he is, an edgy author sperging about Islam in interviews but deep inside he is very fragile. The possibility of an island is his first sci-fi/anticipation novel and as a fan of the genre I love it, and it's not like most French sci-fi which is completely retarded most of the time.
Since we are talking about Houellebecq, I recommend Virginie Despentes aka the female Houellebecq (minus the reactionary ideas, plus the fierce passion), from whom I've only read Rape me and King Kong theory. The first is a novel about two lumpen girls fucking shit up, it's very cathartic. The second is an essay about feminism with some Marxist bits inside, but reads like schizo rambling (I don't think she is schizo though, there's just a lot of info and it's written with a lot of emotion).
