SPOILER ALERT!
Really, it should have a different title...

This book.
It's the second in Karen Chance's series? featuring Dorina.
I had no idea with this book which way was up, down, or any which where and I got lost several times and had to back track.
When she finally got to the whole point of it: the person who's hunting Senate Vampires and killing them and the rune she needed to retrieve for Claire's son Aiden, I was so confused that I practically went to the beginning all over again so I could understand it.
In short, not happy with the second book and hoping the third one is better.
