Descripción o resumen: 1916. The Great War rages overseas, and the whole of Europe, Africa, and western Asia is falling to the Central Powers. To win a war that must be won, Teddy Roosevelt, once again the American president, turns to his top secret Black Chamber organization-and its cunning and deadly spy, Luz O'Malley Aróstegui. On a transatlantic airship voyage, Luz poses as an anti-American Mexican revolutionary to get close-very close-to a German agent code-named Imperial Sword.
