I discovered Terry Pratchett and the wonder that is Discworld about eighteen months ago and I powered through the first four or five books. Then, as is often the way with longer series, I got sidetracked by more pretty books.
So I’m aiming at the Academic of the Unseen University level of this challenge (6-8 books) – partly because it’s a good number and partly cause, well, I want to go play in the Unseen University library!
