Kester is one of the last surviving defenders of the Church of True Light. With the Serpentine Empire closing in, Kester finds himself on a desperate mission to recruit the aid of one of the Church's greatest enemies: a man who is often called a demon. When his ideologies are tested, Kester must choose between upholding the tenants of the Church and completing his mission.

There is nothing Reis wants more than to be left alone to his research. But when the Empire comes knocking, Reis is left with no choice but to fight back. Knowing the imperials will not stop coming for him, Reis is left with one path. If his research is to continue, Marcus Serpentine must die.

Together, the two may have a chance to cripple the greatest military force the world has ever known…if their conflicting ideals don't make them kill each other first.
