So I finished the series. This was way better than the second book, which isn't saying much, but it still didn't live up to the promise of the first book.
I thought it was unfortunate that the witch parts weren't as well-developed as the vampire parts. Well-developed isn't really the right word for it though, since the vampire parts throughout the series were overwrought and complicated. I just don't care about vampires; witches are much more interesting. And there was so much more than could have been done with daemons. I thought all the vampire politics and posturing ended up dominating and pretty much ruining what could have been an amazing series.
