"Arcs of pale lightning flickered around the cannon's barrel, and the sergeant's voice became impossible to hear as the weapon shrieked and growled."

The year is 1919, and Europe lies at the feet of the Kaiser and his hexemeister warlocks. But Russian necromancers have unleashed a plague that will drive the German Empire across an ocean in search of salvation and one final conquest. Standing in their way is an unlikely scattering of allies. Tesla cannoneers and drachenwolf riders, immigrant mages and sewer urchins, tragic U-boat captains and star-crossed lovers. From the fabled walls of Gotham to the spirit-haunted woods of Vermont, they face not only an invasion, but the rise of an ancient, mythical foe, one with the potential to destroy the world of men.
