This is quite a good thriller that keeps you on the edge of your seat throughout. I wish I could have rated it higher however the conspiracy angle to this story seemed a little over-the-top for my taste. (view spoiler)[The fact that multiple officials around the globe were descended from Soviet sleeper agents is within the realm of possibility. These officials, some being third-generation, then being a part of their grandparents' ideological cabal is where I draw the line--especially given the fact that their whole purpose is to bring about the Marxist/Leninist revolution of the proletariat. (hide spoiler)] 
 Overall a decent book for the thrill-seeker, but I would recommend Scott Sigler's works before this one.
