The Silent Service: Virginia Class

I've read the whole series, and Virginia Class was a terrific book. I can't understand the two previous reviews of one star. One of them gave it a "one" because he didn't like it that Al-Queda was the terrorist group they were fighting. (Would it have been believable if they had been Norwegians?) The other reviewer gave it a 1 because he found it less than perfect in technical details. Assuming that the reviewer was correct and the author wrong, I still can't see why that is so important to someone, since it's a novel and not a technical manual. This was a novel that took the series into present times with a Virginia Class submarine. The plot was believable and well executed, with the U.S. contending with the Chinese and Al-Qaeda who have joined together. The characterization was excellent as it is in all Riker's books. I enjoyed it very much and look forward to the next book in this series (I hope!).
