Pratchett was the modern era's prime fantasy writer. In various languages (mostly English) he sold more than 85 million books. He was the most popular author in Britain until he was bumped by J.K. Rowling.
His works, particularly the
Discworld series and a book
Good Omens that he co-authored with Neil Gaiman, were gems of humor, social commentary, and satire. If you have ANY love of humor and good writing pick one up.
My offer, made elsewhere, to send you copies of books by authors whom you like or have heard of free of charge does not apply to Pratchett. My son has stolen all 30 of the books by Pratchett that I used to own.
There are three live action, low key British humor movies of his books. Also about three animated films. I love them all, but they are perhaps a little low key for marathons.
If you can pick up any of his books, particularly from 10-20 years ago, before he suffered from the decline that eventually killed him, PLEASE do so. Google Neil Gaiman's comments and joint interviews w. Pratchett. They are outstanding. Here's the Wikipedia on him. Please read it.
