When I was a kid I used to read tons of books. Now I mostly order technical manuals from for reading, although I still get a bit of leisure reading in here and there. As is par for the course for someone in my line of work, I read mostly science fiction and fantasy in my spare time. Some of the books I've enjoyed immensely:

Chronicles of Amber Roger Zelazny [first 5]
David Copperfield Charles Dickens
Flatland Edwin A. Abbott
Flowers for Algernon Daniel Keyes
The Hitchhiker's Guide to the Galaxy Douglas Adams
Hackers: Heroes of the Computer Revolution Steven Levy
Perfume: The Story of a Murderer Patrick Suskind
A Tale of Two Cities Charles Dickens
