The 3rd book in the series, the second I've read. Great stuff. The problem with so many of the paperback thrillers I've been reading lately is the 2nd Act. Most of them have a great opening, then one good idea that they save for the end. The middle is a vast wasteland. In books like Vince Flynn's Mitch Rapp series, it's kind of the point: after doing something awesome to glean a clue that something bad is going to go down, Mitch Rapp is prevented by bureaucratic red tape from being awesome again until the end. But it still makes for a slow middle.
That is not a problem in the Kyle Swanson Sniper series. Swanson goes from action scene to action scene, using his skills to "rain down pain and terror on the enemies of the United States" (as he puts it.) It's fast, it's violent, it's bloody, and it's a lot of fun. What the authors sacrifice is character (usually Kyle's personal relationships appear only in the first 50 and last 50 pages of the book), but really, if you're picking up an action thriller written by a former sniper, how much love and vulnerability are you expecting?
One major flaw is the way Coughlin sets up the Arabs (in the two I've read): they're all either noble men who appreciate military efficiency, or noble women caught up in the evil actions of their rogue nation, or they're just straw men that he sets up so that Swanson can knock them down.
Even Juba, the rival sniper that's been the villain in both books I've read, started out in DEAD SHOT as an interesting character, but here in CLEAN KILL he's been reduced to a cold, revenge-is-the-only-thing-on-my-mind assassin.
But, what the hell: the action is superb, and like all dudes, I love me some snipers. I'm gonna go back and read the first in the series: KILL ZONE.
