The 41st and final Discworld book by Terry Pratchett, and the fifth about Tiffany Aching. After the end of the book, the editor's note says that Pratchett's normal method of writing was to get the beginning, ending, and middle in place and then spend quite some time going over the details and revising and polishing and revising again. This book was missing that polish, which the note acknowledges. Pratchett wasn't able to "finish" it in his usual way, so although the framework of the story is there it doesn't feel as complete and polished as his books usually do.

Still, there is a complete story, a new and interesting character joining the witches, and continuation of Tiffany's story, so it's a good read for Discworld fans, but it does feel as if some of the plot points and characters are missing depth they probably would have got if Pratchett had had the time. Very sad to have finished this book, now knowing there will never be a new Discworld book to look forward to. :(
