I thought that Swordhunt and Honor Blade were both very dull, especially. I know that those were originally supposed to be a single novel and they got split into two separate books in order to avoid a hole in the publishing schedule after The Empty Chair was delayed. Even though both books are rather short (220 pages each), I wonder if they received extra padding when they were separated and that slowed their pace down.
I don't think there was enough time for any rewrites like that. It looked like they just split the existing manuscript in two. They didn't even renumber the chapters for book 2, just started it with Chapter 6.
