Meh. That was my first reaction when I finished the book.
Since I have been out of reading for so long, and my main bulk of reading is not done in the department of this particular genre, I cannot say whether my 'gulping' of the book, i.e. reading it cover to cover fairly quickly, is due to the writer's abilities of pulling a reader in or my need to know the end (and no, I cannot jump to the end and just be done with it, I have the compelling urge to travel the literary road completely, start to finish). So the first, and one of the only, point for this book is the way it dragged me in and made it hard for me to put down. As a result, I finished reading it at 3 in the morning.
It is an easy read, fairly straight forward (in general), and moves along quite quickly. You don't tread in place for very long, or at all. However, it does leave some scenes wanting, though it is not plagued with the had-an-idea-so-I-ran-with-it-but-forgot-to-go-back-and-add-details feeling.
I do not expect every adventure/mystery novel to be a completely surprising. They rarely are anymore, the basic twists and turns are pretty much expected. However, too blatant foreshadowing ruins even the most trivial story lines. First Person Narration is mostly hurt (if not mostly plagued) by it, because once a character hints at a possibility and then ignores it, big, red, neon signs are lit up "danger, danger". When it is repeated, it also makes the character seem, well, to put it bluntly, dumb. Add to that a character whose mantra is "don't think", and you, as a reader, get the feeling that someone offended your intelligence.
Also, I know that most books have an agenda, a point, other than the plot, that they want to get across. Well, not books, but their writers. I'm aware that the matter of subtlety in this matter has been lost, or, rather, the ability to pass said point elegantly. While some books shove it down your throat, others, as this book, manage to make it quite delicate. Problem was, that while delicate, a) it could be seen a mile away (though I've already mentioned the subtlety issue); and b) it was not compelling.
I did not read the opening notes (I never do before I read the book, a clean start), so I did not know what he was aiming at, but it was pretty clear almost for the start. To make it clear, he's trying to make a point about PTSD and the society's handling of army veterans in general. While it was obvious he aimed at these issues, I felt he missed them. I felt the main character was messed-up before he joined the army (with the very little information we have on how he was before), and afterwards he just seemed psychotic regardless of his service. I think bringing this very important issue on the table requires a different genre altogether, or a longer and more psychological book, one that isn't focused on the action, but rather the REaction.
Despite the good intentions and the characterization of a man incapable of real emotional connection who's trying not to think, it didn't come off as a PTSD, but rather as an obnoxious and unrelatable character. It (the book, the story, the character) needs more depth, more poking fingers into the unpleasant places. More rawness, jabbing a hot poker into the wound. It's a bit too willy-nilly on this important issue.
I have trouble with books where I find the main character unpleasing. It is a serious problem when the terms I'd use to describe a character are: Stupid, emotionally numb, and psychotic. Of course, when we're talking about a character who is supposed to evoke empathy, it is even worse.
At the end, despite all that happened and could happen, two things occurred that annoyed me:
1. A forced happy ending - I am quite allergic to those, especially in non-romance literature (not that the forced happy endings in romance don't give me the hives, it's just they are more genre acceptable). While I guess some would argue it is not necessarily a happy ending (it is quite an open one), I still feel it is, especially because it feels forced. It doesn't feel natural, just sort of a filler to tie a loose end and to give hope to our beloved hero. I would see it end in a completely different way.
Mind you, I am talking strictly about the last chapter, an afterward of sorts, and not the resolution of the mystery plot. It (i.e. mystery plot) was resolved, if not to my satisfaction, to an expected and presumable outcome (if you accept the premises in the plot up until then, that is).
2. Despite all that has gone through, despite all the realizations and enlightenment our hero had gone through, he has not evolved or grown one single centimeter. He stayed the same, but, mainly because of point 1, it doesn't seem like a human being that got stuck in place, rather like a book character that has not evolved. And in such a story, with such revelations, progress must be made.
To sum it up: I didn't like the main character, the moral seemed forced, and the ending fake. However, it is written in an engaging way, and the action plot is quite an interesting one (though not entirely innovative). I probably will not read this book again, but I cannot say that I would stay away from other books by the same writer.
