This is not a book I found particularly enjoyable. Too many stereotypes in cliched situations leading to predictable conclusions. The book reads more like a comic which I think is due in part to the lack of any character depth or subtlety as they develop through the story. A bit of light and shade would have helped to make this feel more believable but unfortunately the key characters do not exhibit any of the vulnerabilities or personality that might have made them appear more realistic. The story is also very short so the above comments may well be a symptom of this. If so, I don't believe the length can be blamed for what I found ultimately to be a corny story. At times I found the narrative amusing even though I know this was not intended. I was reminded of lines from the Naked Gun films when a response given by a character seemed wholly inappropriate for the situation such as some of the exchanges between different FBI characters updating one another with developments as the story unfolds. Lastly I found the style in which the book is read to be quite tedious. I understand this is a tense thriller but for me, the narrator over-does the macho way he reads the book. I understand this is intended to echo how the main character comes across such as the way he responds to threats and danger in a clinically and emotionally detached way. I consistently found this dramatic emphasis went too far.
