anyone have a recommendation for a good book or series of books?

at the moment, feel like something historical fiction or non-fiction, fantasy, sci-fi or in any way generally thought provoking...

@bright_moon have you tried any Gene Wolfe?
@jec no I haven't read any of his. I've so many books to catch up on.
would you suggest any specific one to start or are all his books very good?
@bright_moon I'm not sure I would call his books "very good" but I did enjoy reading Book of the New Sun. It is very complex and multi-layered so you have to put in work as a reader.
@jec oh, that's no issue. I don't mind putting in the work. As long as they make me think in some way I'm happy to try anything.
