I'm not sure if anyone else has read this, but I've just read that he finished the next Tiffany Aching book in the summer and it's going to be released sometime this year. I'm going to be crying all of the way through it, but it's a comfort, no matter how small it may be, that we haven't quite read the last of him. It also warms me a little that his last one is around the character he's "had a particular fondness for" to paraphrase an interview I found earlier. Even in the end, it seems Mr. Pratchett's had one more trick up his sleeve for us, and has given us a goodbye. The greatest magician who ever lived. Excuse me now, I feel the tears coming again.
