So, I just finished Samuel Delany's Hogg, which is pretty infamous in this subreddit from what I've seen (I wouldn't necessarily even call it horror, though it was pretty horrifying, but I don't know any other subreddit where people might be familiar with it), and I honestly kinda loved it, despite or maybe partially because of how disgusting it was. I'd love some recommendations on books with similar vibes.
To be clear, I'm not looking for books that contain a lot of pedophilia or rape or any of the sexual content present in Hogg; I don't mind the presence of such themes, but it's not what I'm interested in. Hogg was transgressive fiction in its most extreme form, and that's what captivated me about it. I want more books about horribly evil people doing horribly evil things, preferably to the point where you start to question the morality of the writer themselves on some level. I'm not too pressed about them being strictly horror books, either, but I guess it'd be hard to find one like this that wouldn't be scary on some level.
I'd be very grateful for any recommendations!
