Like we don't have enough blood suckers in Wahsington as it is, but this guy is okay. This book was something slightly original in light of the thousands of vampire books lately. The thing I honestly liked the most was the information regarding the species at the beginning of nearly every chapter. There were several different methods, snippets pulled from the Nightmare Pet file, or audio transcripts or documentation of presidential events that the author was able to intertwine into his character. I think that is one of my favorite things in novel writing, incorporating big historic events to make the fictional story seamless into real life. 
 Now onto the drawback that I had with this book, the vampiric main character. Waaaaay to serious all the time. He has not a bit of humor and he was so stoic and bland that he became a little non-interesting to me. Just one word answers most of the time and his dialogue matching his boring demeanor. And -SPOILER ALERT - SPOILER ALERT - SPOILER ALERT - Letting the bad guy escape at the end was pretty absurd. He could have totally killed/incapacitated that guy before heading back to stop the other threat in Washington DC. 
 Other than that I don't really have too much else to say on the subject of this particular series. This will get 4 stars, because I think it was better than average and it warrants an extra star. End result - I might check out later books to see if Nathaniel Cade perhaps develops a sense of humor or maybe learns a few more words of the English language when he speaks.
