I enjoyed this book, but I'm not rating it higher because it took me months to read. I kept getting distracted by other books, which tells me that as much as I liked the storyline, it wasn't hooking me. I suspect it's partially the lack of chapters in the Kindle edition (not sure if Terry Pratchett did chapter headings in his hardcopy books or not as I've only read them on the Kindle so far). At any rate, I enjoyed the social commentary immensely. I love the philosophical edge of Pratchett books.
