This is a model of its type, engrossing and authentic in details of naval life. I'm sure the helicopter scenes are accurate beause the author is a helicopter pilot, but other details ring profoundly true as I've had a certain amount of sea time on Navy ships myself. I know what "Midrats" are and such authentic details flesh out the story.
But of course it's the plot and the characters that drives it, and the author has invented a complex but all too believable plot. He's given us good heroes to admire, a main character Chase who's the brother of David, the hero of book 1, and as I've said in earlier reviews, having a good villain is every bit as important. In this book, the incredible villain he created in volume 1, Lena Chou, comes back with a vengeance. She's "almost 6 feet tall" (I understand there's actually a place in China where people are exceptionally large, so the stereotype-bending aspect of this might not be so extreme as it sounds), beautiful, extremely athletic, and a total sociopath without the slightest twinges of conscience, in fact, she enjoys watching her victims squirm as she tortures them to get the information she requires. The only slight criticism I might make is that the author deliberately introduces her under an alias, and while he does say she has dark hair, he doesn't tell us she's Asian until her cover is blown for other reasons. In retrospect this seems to be taking suspense too far, as I didn't realize Lisa and Lena were the same until she'd met Chase and the plot thickened.
The action happens in Dubai (I've never been but the description seems believable) and on the high seas. This is the kind of book you can't stop reading till it's finished. Any reservations I had about the series after reading volume 1 don't apply to volume 2. It's a great series and I'm going to read volume 3.
