Mason imagines a very different outcome in the post Iraq war era, and populates his story with a band of organized and dedicated ex-service men (mostly) who decide--with very little prompting, it seems to me--to take matters into their own hands and remove a lingering middle-eastern problem. Mason has actually hatched a very intricate and elaborately planned mission, that he spins out for us as it takes place, keeping the reader wondering where this team is headed, and how they'll accomplish what they've set out to do. The story is well paced, really well thought out and suffers only a bit from a huge cast of characters that is at sometimes a little difficult to keep track of. the main characters seem pretty well flushed out, but the other are almost inter-changeable in a lot of ways.
There were a few sub-plots that kind of seemed like Mason had cooking, and then sort of let them boil off and come to nothing. The final story may have been better without them, but who's to say. It was fun to read an alternative history, and also fun to read something a little different than the regular stuff I read, if you can call the range or stuff I read regular.
I would have read something else by this guy, but it doesn't look like I'll get the chance unless he cracks out something in the future!
