It is year 142 of the German World Empire as reckoned from 1933 when Adolf Hitler became German Chancellor and the vilified Nazi regime was born. Dr. James Silverthorne, tenured history professor at Goebbels Institut in Greater Denver Gauleitung, Colorado Province, is also a seasoned time traveler vetted by Reichskounzel to conduct retrotemporal research in selective epochs of the past. James plays the key role in a desperate conspiracy designed to obliterate Deutschesweltanreich in retrospect via a clandestine return to wartime Berlin to locate and hopefully thwart the efforts of Nazi hero of heroes Erich Lustmann, a former SS officer sent back to 1939 decades after the war by Odessa SS exiles in Argentina. A postwar "secret weapon" unknown to the allies, the Lebe Technique developed by a Nazi theoretical physicist permits Lustmann's successful dispatch into the past. Armed with prescient knowledge of wartime events, he somehow influences and rectifies the action-decisions of the Nazi hierarchy, and thus enables the Third Reich to become the World War II victor, not the vanquished. Fearing his "mission impossible" is precisely that, Silverthorne nevertheless pursues his world-changing crusade in an exciting time travel adventure that is grand in scope as well as purpose.
