In this gamble, more than a few poker chips are at stake. When an Army Air Force Major vanishes from his Top Secret job at the Fort Worth airbase in the summer of 1947, down-on-his-luck former Ranger Jefferson Sharp is hired to find him, because the Major owes a sizable gambling debt to a local mobster. The search takes Sharp from the hideaway poker rooms of Fort Worth's Thunder Road, to the barren ranch lands of New Mexico, to secret facilities under construction in the Nevada desert. Lethal operatives and an opaque military bureaucracy stand in his way, but when he finds an otherworldly clue and learns President Truman is creating a new Central Intelligence Agency and splitting the Air Force from the Army, Sharp begins to connect dots. And those dots draw a straight line to a conspiracy aiming to cover up a secret that is out of this world?literally so.
