In an alternate 19th century, the American Civil war has raged on for twenty-five years. While Unionist partisans dig an underground railroad beneath the mountains of Arizona, an adventure is set in motion that will change the fate of the world. From the bar room brawls of seedy Tombstone to the crumbling pueblos of the arid wilderness, the race is on to discover America's Golden Heart. More
In 1861 the Confederate States of America fired on Fort Sumter beginning a civil war that tore the continent apart. In 1862 southern miners discovered a rare ore that burned ten times more efficiently than coal. It was called ‘mechanite’ for its role in an industrial revolution that changed the face of war. With both sides in possession of terrible steam-powered war machines, the conflict has descended into a stalemate that has lasted twenty-five years. In this prequel to the novel Golden Heart a battle begins that could decide the fate of America itself.
