Born in the American West to a clan of cowboy anarchists, Dawn Rae Bjornberg is raised in post-Revolution Leningrad by her father, a party-line Leninist who re-christens her Aurora. She spends her early years in Russia but then grows up as a teenager in Montana, before being drawn into gun-running and revolution in the streets of Washington D.C. during the depths of the Great Depression. When a surprising revelation about her past puts her in the crosshairs of U.S. authorities, Dawn returns to Russia, where she is groomed as a spy by the organization that later becomes the KGB.
