I found a lot more explaining' in this book than in the others, explaining of things that the operatives should have known, and so were explaining for my benefit. That's a pet peeve of mine.
That aside, I enjoyed the conclusion (I assume) to the series. The traitor is found out in this one. I thought that this entire group of CIA black ops was very trusting and seemed awfully naive. This was the book where that seemed really apparent to me. So I can't rate this as high as the others, even though I liked the nonstop action and the nuke plot.
