Not sure what your demographic is? But you can add 22-year retired USAF instructor pilot to it...thoroughly enjoyable. I joined G.R. to commend you for the sense of authenticity you've given the "military" interactions throughout the Odyssey 1 books. It's tough to nail the insider feel to the slang, banter and protocol w/o bogging down. (You're at about 92%, which is superb.) Thanks, keep them coming downrange.
