Born in the U.S. and reared in Mexico, Harrison Shepherd is a liability to his socialclimbing flapper mother, Salome. Making himself useful in the household of the famed Mexican artists Diego Rivera and Frida Kahlo, and exiled Bolshevik leader Lev Trotsky, young Shepherd inadvertently casts his lot with art and revolution. A violent upheaval sends him north to a nation newly caught up in World War II. In the mountain city of Asheville, North Carolina he remakes himself in America's hopeful image. But political winds continue to throw him between north and south, in a plot that turns many times on the unspeakable breach - the lacuna - between truth and public presumption.
