I think I may read this one, though I'll probably wait until it comes out in paperback. Don't worry about spoilers on my account, though.
I'm not expecting a well-written book, given that it sounds unpolished and incomplete (and I could barely make it through Snuff). But it sounds like Pratchett was saying farewell to his characters in this book, and I
am curious about that.
Actually, you can thank the Guardian review and its spoiler for my interest.
I had completely lost interest in any new Discworld books until I read it.
