Since this was alternative history (and a mix of a handful of other genres), it was disappointing to see women's roles largely unchanged.
That being said, I liked Adele a lot. The authors could have made her weak and stupid, but they didn't. Flay was also a great villain.
I wondered at the Greyfriar's identity. His secret doesn't come as a complete surprise, but it's still a good twist.
I really, really don't like Senator Clark.
With all the books out there featuring vampires as good, this was different. It was refreshing to read one that the vampires are evil, horrible things that hold absolutely no regard for human life.
