The story started like a roller coaster in the middle of London where Jack Ryan, an American tourist, foils the attempted kidnapping of members of the Royal Family.
The book could not keep a steady pace from there and at times became so slow that I literally had to skip pages to get to the action. Tom Clancy's natural descriptive style and obsession to get the facts absolutely right almost spoiled what otherwise could have been a very good espionage book.
What works for the book is the character of Jack Ryan who shows a wide range of emotions. Also, the early part of Miller's story was very interesting. Although there were very few actions scenes, they were very well written and the climax was satisfactory if not exceptional.
However as the story progresses it becomes extremely difficult to believe the things that are happening. The helplessness of so many security agencies followed by the near invincibility of the terrorist group. Also, all throughout the book, the ULA are described to be very professional in their approach but in the both the times when they had their targets within reach they committed elementary mistakes. That was a bit hard to digest.
Overall a nice read for an action/adventure/espionage fan and a must read for people who want more of the Jack Ryan character.
