Fulcrum, Book 1: The Rot Has Set In - Fulcrum, #2

The Citadel of the Almighty is, for all intents and purposes, the center of the world. Not only does it lie in the borderlands between the realms of the Skanda and the Arganian people, an oasis in an unhospitable river basin, it is also the holiest of holies, the sacred home of the United Church. Once already, war started here. If the world is to change again, here is where that change will begin.
As winter sets in, Citadel Town prepares itself for another season of cold and isolation. But things heat up when early snows trap pilgrims and mercenaries alike in town, and it doesn't take long for unrest to break out. Captain Tygg Vana of the Church Guard struggles against archaic rules for the power to keep order in his streets--while on those streets washerwoman Ahlin's struggle against freezing cold and violence soon becomes one of life and death.
