I found the characters mildly interesting at first, and I liked the setting of the story. That's why I gave it two stars rather than the one that it probably deserves. I have to say, I'm just not seeing where all the positive reviews are coming from. To begin with, there is really nothing special about the main character, except that he's kind of an idiot. They set him up as some kind of impressive Army sniper, but there is no evidence of that in his actions or the way he approaches his challenges.
The love interest is shallow and uninteresting, but the cardinal sin, in my opinion, for an author writing a mystery/thriller is to come up with a weak, unrealistic, and silly antagonist. In this novel the bad guy is laughable. His motivations are really contrived, and the explanations for what he is doing seem like an after-thought. Law enforcement are treated as complete morons throughout the book. The plot is ridiculous. Don't want to ruin anything for those who intend to read this drivel, but, for example, Army captains don't do what one of these characters does toward the end of the book, especially not in response to what is portrayed as a fairly casual affair.
Dialogue is bad too.
