Shadow of Night
While I loved the historical and scientific aspects of the first book, I found this book really slow and uninteresting. I found Diana and Matthew to be annoying at times, and I'm over the whole "I'm a territorial vampire with anger issues" act that Matthew portrays. Somehow I was able to tolerate it better in the first book, but it was too much for me this time. It's a shame, because I'm a big fan of Elizabethan England and anything Tudor, so I was looking forward to reading this.
