Or, failing that, I'd quite like to read one of the many mystical tomes Pratchett made up. Particularly the Ego Video Librum Deorum, if only for the naff latin.
No doubt! Pratchett made up quite a few books. Wonder why no one's taken a stab at writing one of them. There are silly copies of The Necronomicon floating around. I was sucker enough to buy one when I was a teenager.
