This is the first time I have not finished a Clancy book. It is complete nonsense, with no sense of suspense, mystery, or even a half decent plot. I realise that this based on a computer game, but it is nothing more than an American nuclear submarine blowing everything up in its sights, with no story or even a perceived threat to its own existence. Another reviewer made a reference to the poor quality of Clancy books which are 'based on' or 'created by' etc. I agree - stick to the Jack Ryan books and you won't be dissapointed; otherwise, avoid them like the plague. I wouldn't even give this book 1 star, but that choice was not available. The worst book I have read in many years!
