Three men who would be king threaten to sunder a kingdom, provoking a war that will drown its lands in blood. Amid the backdrop of a new Cygnaran civil war, the fate of the kingdom depends on the outcome of a covert struggle between two powerful warcasters—the gun mage Allister Caine and the mercenary warlord Asheth Magnus. Caine faces a moral quandary as he seeks to kill the bastard son of Cygnar’s former king, knowing he must end an innocent life to preserve the peace. But Magnus is equally determined to see the bastard crowned as king—and is willing to kill anyone who gets in his way. Regardless of who emerges the victor, the blood of kings must be spilled to end an otherwise interminable war.
