Synopsis: The North American continent is made up of several rival nations, and a Cold War is building among them. The Nazis rose to power a decade ago. People travel by airship, and powerful organizations calculate with Babbage's Difference Engine. The Nazis have hatched a plot to raise a legion of undead soldiers. Enter Sean Fox Rucker and Jesus D'Anconia Lago, two Great War veterans and freelance pilots who are pulled into the quest. They are joined by a brash Greek merchant, a brilliant Jewish cowboy, and the woman who once broke Rucker's heart. This ragtag band of reluctant, bickering, swashbuckling heroes is soon locked in a globe-spanning race against Nazi occultists, clockwork assassins, and a darkly charismatic commando. In a world where science and the supernatural coexist, and the monsters of legend are as real as the necromancers who summon them from murky realms, our heroes alone stand before the rising shadows. But all their efforts may not be enough.
