I think I love you a little.
I'll bounce between fantasy/sci-fi, mystery, and specific non-fiction. I just finished reading this book called "Eats, Shoots & Leaves" which is all about punctuation, and I'm such a nerd for loving that book as much as I did. Besides that I love the really old british mysteries written by, say, Doyle or Christie or Marsh.
I'm at the stage now with the Foundation series by Asimov, where I'm eyeing the books in a semi-threatening manner, which is prelude to the actual reading.
