The Great War, 1918. With no end in sight, dark forces have entered the horror of No Man's Land to secure victory or Armageddon. Swept into their currents are two figures who will shape the final blow. Warren Bishop, con man and coward, is killed by his own dead brother in the lunar hell of France and reborn to serve the Lost Battalion, the army of war dead serving a mad sorcerer. Meanwhile inventor Vasilya Savorov, illegitimate daughter and heir to the Fabergé family fortune, has been kidnapped by the Germans to make a mechanical nightmare to break the deadlock of war and secure victory for the Kaiser. As fate draws them together the future of millions lies in the balance. Victory or defeat means a cataclysmic Harvest of Blood and Iron.
