Just to continue the TOB thread that was so rudely interrupted...
Actually, not less than two books have come out since we were interrupted: The Long Earth, and Dodger.
I just finished Dodger today. I thought it was top-notch Pratchett, and it was a first for him: no magic, no alternate universe, no alternate Earth history, in fact absolutely nothing supernatural at all. In fact, it takes place in Victorian London, and many of the characters were in fact real people.
The Long Earth, on the other hand, took a while to get going. If I remember, it was quite a few chapters before I really got in to the story. But once I did, it made compelling reading. The fact that it was co-authored with Stephen Baxter probably accounts for the fact that I didn't really discern Terry's "voice" until about half-way through, and only fleetingly at that.
What I'd like to know is, how much of it really is Pratchett, and how much is Baxter?
Edit: I just noticed I used "in fact" three times in my third paragraph. How embarrassing
