The Serpent's Gambit

First one, then four. Four sets of human remains with alarming things in common. All four had been military active duty. All four had disappeared from Roswell Army Air Base in 1947. All four had the same physical anomalies. All four had military records that were classified. Unraveling the cord of mystery takes local citizens and a small knot of Army personnel on a trail that leads through Area 51 to the White House, from Moscow to deep space, and through a maze of people who are not who or even what they seem to be. Who do you trust, if anyone at all?
