On CD I just finished listening to The Big Sleep. (If you're gonna read the classics, then in my opinion, you just oughtta read the classics).
It's been years and years since I reread it. The man was ingenius.
I'm also listening on CD to A Princess of Mars. It's been years since I re-read that as well, and Burroughs was a brilliantly good writer. I realize that more and more now that I am much older, and am reading his books not so much for story as for style and capability. The man had a superb use of the language. I was also shocked to find out not long ago they were making a film of the book. Not something I'd think Hollywood would have much interest in.
Since I'm going through the Great Books of the Western World in order I've just started re-reading Herodotus.
Other than that been too busy to read other than for work and research.
