Honestly, I am not sure if I would have enjoyed the story written in a book. I listened to the audiobook which made it certainly easier. This is a political thriller about a driven CIA agent, determined that 9/11 won't happen again. He would give everything for his country. Everything certainly means he's endagering the women he loves.
A lot of spy, a lot of deaths and a lot of CIA mumbo-jumbo.
For me the narrator, Dick Hill, gave the story a whole new flair. His capability to speak in different accents and even in different languages filled the audiobook with life.
