What a refreshing book! The twists and turns were invigorating, and I really liked full presentations of the characters. I would say that I figured out the villain before the end, but that wouldn't be completely correct; I had a list of possibilities, but the actual ending really was a surprise.
I'm not sure what it was that grabbed me, but the main character and his assistant were both intriguing and complex. I'm still waiting for her to gauge her fiancé and go for Stryker, but that's for another time. Great book!
