Greenwood of the Fey Sovereign

From publisher blurb:

War is looming. The Earl of Nanch and his neighboring elven kingdom are sharpening the spears of aggression. Those on the border are split between two dangerous dynasts. Pressed into duty for lord and country, the peasants and gong farmers of Nanch find themselves in a strange and unnerving forest full of denizens older than the practice of naming. In this new world, the rules of life and death are a game of whimsy practiced by fantastic forces, and bizarre ancient feuds re-ignite in the chaos of war. Those errant attendants of Nanch will be fortunate to survive the madness of either ruler!
