Yes, I read this one out of order. Oh, well. I like this series, but my favorite characters are the military/assassin guys. After I read about Vince and Keegan, I just couldn't wait through 9 books to read about Devin and Andrei.
If you're following the series, this one is quite good. I enjoyed the mystery of who was trying to kill Andrei. The solution to Devin's animosity to Andrei is an interesting twist.
