"The Shepherd's Crown" was good, though a little rough in places. Though as the afterword notes, Pratchett had 'finished' the book at the time of his death but perhaps had not really finished it - he would probably have spent some more time polishing it up before publication.
But, in many ways, this was a perfect last novel to go out on.
I also raced through "Shada" over the weekend, which was a fun little read. Gareth Roberts was obviously enjoying himself emulating Douglas Adams' style. It did remind me that the classic Who did tend to love to use utterly-inescapable-and-yet-easily-resolved cliffhangers, though.
Next up will be "Pirate's Prophecy", the latest Pathfinder Tale, and the third starring Torius Vin. I enjoyed its predecessor very much, so am hopeful for this one, too. And then the next is "Breaking the Bones of Hell", Pathfinder #102.
