A short, curated guide — not an automatic related dump. Figures come from SubMouse's safe-for-work directory when we have them.
r/books (about 27.3M members, directory rank #18) is a large moderated space for in-depth book discussion. It is not always the fastest place to get a personal recommendation, and it is not a specialty genre board.
The six communities below are drawn from books' directory related list and SubMouse relevance ranking (suggestmeabook, booksuggestions, Fantasy, literature, comicbooks, horror), with purpose notes so recommendation threads and media-adjacent horror talk stay distinct from the main books hub.
Use r/books for broad reading discussion. Switch to suggestmeabook or booksuggestions when the goal is "what should I read next," Fantasy or literature when you want genre or deeper lit norms, comicbooks for graphic novels, and horror when the interest is horror entertainment including books rather than general fiction talk.
