Cryptonomicon - Neal Stephenson - Second time through. Read it years ago in hardback, but I think I'm enjoying it more this time. Nice to have the dictionary available when Neal uses big words I don't know.
A People's History of the United States - Howard Zinn - This one is thanks to a discussion here on MR. Interesting take on US History.
Witches Abroad - Terry Pratchett - Love Terry's Discworld books.
Oh, and about 80 more on my Kindle...
