I've read quite a few things. For/at work I've read Imperium by Robert Harris several times, The Afghan by Fredrick Forsyth, and almost all of the Old Testament, which has pushed over the line into agnosticism.
I finished 2001: A Space Odyssey. It was good, certainly clears up a lot of the mystery of the film...which makes it not as good in my opinion.
Also read The Little Price, which was a great little children's book, which has a lot of depth to it which makes it incredibly appropriate for adults as well.
I am now reading another children's book called Private Peaceful, which deals, among other things, with WWI. I'm interested to see how it's dealt with in a children's book.
