Vengeance trilogy

"They call him the Usurper. Once the Kisian empire was ruled by gods. Now Kin Ts’ai, a man of common blood, sits on the Crimson Throne. At his command, the last Otako emperor was executed and a new era began. But claiming an empire is easier than holding it. In the north where loyalty to the Otako name runs deep, a rebellion grows. And Emperor Kin will learn that killing one Otako, doesn’t mean you’ve killed them all. Vengeance is coming."--back...
