I didn't know much about Pratchett - I didn't even know he had a long-time assistant who also was a dear friend. And what a difference it made! Not only can someone who was close to the action re-tell a lot of it, but one could feel the affection between them from the entire text. Wilkins clearly learned a thing or two, because he did manage a few bits of pratchettian humor as well, to say nothing of the omnipresent footnotes. And he also narrated the audio version of the book. Very much recommended.
