Non-fiction isn't exactly the thing I pick up when I'm bored, so I can't really say which non-fiction is great and what isn't. I just think that any book I can get through is good in my opinion. Also, I think it's sometimes hard to make people like certain genres, so even though some people are excellent in their subject areas, their subject areas can be quite dull. One example is Jared Diamond's book, Guns, Germs, and Steel. I can't exactly say that history is my favorite subject, but Diamond makes the book easier to read. He uses many different sources and explains his position, allowing us to understand what's going on without knowing previous occurrences. He uses many pictures I mean charts, and you know we all love pictures in a boring, I mean educational book. So although I don't think Diamond is as interesting as Stephen King, or Anne Lamott, Diamond is still my favorite because he takes something boring and turns in interesting enough to able to read.
