Renegade Crowns (2006)

From the back cover:
"South of the Empire stretches a broken land, a patchwork realm of petty kingdoms and principalities. It is a region fraught with warfare, shifting alliances and broken treaties. In the Border Princes, a common man can rule, rising above his meagre station and making his own destiny. But no throne is secure, for in this land, a knife in the back or a poisoned cup can change the world, toppling the greatest lords and elevating the lowliest of wretches to take their place. This is the Border Princes. This is the land of the renegade crowns."
