This collaboration represents the first foray by Neil Gaiman into novel writing (as opposed to graphic novel writing, in which field he was already famous for Sandman). It doesn't feel like a Gaiman book at all, though. The mass of one-line jokes, repeated jokes and bad puns seem entirely Pratchett and they are unrelenting. The weird thing about them is that they didn't seem that funny. Not unfunny, just for the most part mildly amusing, rather than raucous belly-laugh inducing. I remember the other Pratchett novels I've read as funnier than that - but that was many years ago; maybe my taste has changed or my memory is faulty.

The funniest aspect of the book is the plot which involves the imminent Apocalypse, as predicted by the sub-titular Angnes Nutter. This book is mildly subversive (if you are Christian) in its suggestion that humans can create enough evil for any purpose without requiring any external supernatural influences. Such thinly disguised "messages" also remind me of the other Pratchett novels I've read. Whatever contribution Gaiman made, it didn't show up as distinctively his at all.
