The Blade Itself (The First Law Trilogy, 1) - Abercrombie, Joe

They say Black Dow's killed more men than winter, and clawed his way to the throne of the North up a hill of skulls. The King of the Union, ever a jealous neighbor, is not about to stand smiling by while he claws his way any higher. The orders have been given and the armies are toiling through the northern mud. Thousands of men are converging on a forgotten ring of stones, on a worthless hill, in an unimportant valley, and they've brought a lot of sharpened metal with them.
