I just finished the book on Saturday, Got the book from Borders about one week ago.
It was an interesting read, a nice mixture of DS and the Bunny Information. It was a quick read. I hadn't read her earlier fiction so I don't know how that went.
As you read it, you don't know how much of the behind the scene stuff was just made up, or was it true.
I think if it does well there will be a sequel, just how the book ends.
