I read fiction and non-fiction. I like historical books, both fiction and non-fiction, and some science fiction, and hmm like family sagas with all sorts of family secrets and odd relationships, and current events, and memoirs, and like dystopian and/or post-apocolyptic stuff (but pref. not YA - don't like to read about teen love triangles), and humorous stuff like David Sedaris and that kind of thing, and really whatever looks like it might be interesting even if it isn't on my list. I don't generally like mysteries, don't like romance novels, don't like anything written in a formula, because I don't like knowing everything that is going to happen within three minutes of opening the book.
I basically read whatever I feel like reading and I reject the idea that people only read this or that based on type. It would probably be more useful to figure out what type a particular author was and people who like that person's books might have a compatible type. For instance, I hated the book Julie and Julia, and it was totally because I could not STAND the woman who wrote it. About herself. I got so annoyed by her that I just stopped reading it pretty early on. However, that subject would generally be really interesting to me. Just not if she's involved.
