content: I found the book to be difficult to enjoy because the writing was immature (too cliche, descriptions were ineffective). I also had trouble with his description of terrorist actions. For example, it's impossible to silence an AK-47 because the bullet always leaves the barrel at supersonic speeds. Anyone who tries to use this in a thriller doesn't deserve to be published.Mr. Robinson may know a lot about subs, but I couldn't get past the first 2 chapters to find out. Sorry.
