Abraham Lincoln warned that "the approach of danger" to our Republic would come from within, that we would be the "authors of our own destruction". Lincoln was confident that "all the armies of Europe, Asia, and Africa combined . could not by force, take a drink from the Ohio, or make a track on the Blue Ridge, in a trial of a thousand years." The stability of our representative democracy is taken for granted by most Americans. And yet, a careful study of history suggests that economic, social, and political forces at work in contemporary America and the world at large represent significant internal and external threats to the greatest republic in human history. The first two volumes of this fictional trilogy were concerned with internal issues. Alexander the Great, 63rd President of the United States depicts events Lincoln assured us could never happen. But the book also celebrates the resiliency of the American spirit and ends with the promise of restoration of the American Republic.
