To be honest most of the books I have aren't really what you'd call classics, they tend to be more of a factual/humourous nature or a diary rather than an full-on story. The last 'diary book' I read was Kevin Smith : My Boring Ass Life So Far. It was pretty good, and funny as well. The next book I have to read is called Cannabis, I saw the title at the shop and it seemed like it would be a good read, but I haven't gotten round to it yet, much to my annoyance.
As far as manga goes, I probably have more manga than I have books, although I only have manga consisting of three series. Volumes 1-4 of Lucky Star (obviously), volumes 1-8 of Rosario Vampire and volumes 1-14 of Chibi Vampire. The latter, while predictable as far as plot is concerned, was also fun to read as you can appreciate the art that is there as well.
So in the end I voted for both in the poll.
