Terry Pratchett was a master of the art of British comedy. What's more: he was one of the great fantasy novelists and satirists of the 20th Century. In being all these things, he is - at least in America - often unfairly overshadowed by specialists in each. He created a famous black-haired, bespectacled young wizard who goes to a school in a castle, and then a young upstart came along and stole his thunder. A successor to Monty Python and P.G. Wodehouse, a contemporary of Douglas Adams, he was a bit more serious than any of them. The breadth of his invention rivaled Dickens, but then, he wasn't Dickens. And of course, Pratchett was far too funny to be taken seriously as a satirist.
