This is the tragi-comic love and war story of Reginald (British nobility) and Vivian (Austrian Countess), who meet at the 1908 Paris Air Show and become lovers. When World War I broke out in 1914, they each became fighter pilots for their respective countries. This book describes the unusual and unique adventures they have had separately and together, both during the war and afterwards. When the war ends, they get together in the United States of America, where their further adventures include flying onto a mesa, which is fully occupied by a technologically sophisticated native tribe, meeting up with a ghost squadron of dead pilots from the war, and organizing an early airline.
