Ironbound- Cold Wind (Ironbound, Book 2)

Lost and forgotten, Castor is a prisoner of the very Iron Empire he once served. Thought of as a common criminal, Castor guards his dangerous secret—that he has bound a second Symbol—with his life. If the Censors knew, they’d execute him on the spot. There is only one path to freedom and avenging his family. He must earn it no longer as a member of the Iron Legions, but by spilling blood for one of the great Houses. The dead gods stir in their rotting slumber. Dangerous enemies stalk his new master. Surrounded on all sides, Castor must learn the secrets of his Cor Heart and reach new heights of power before it is too late. And in the wake of his Ascent comes the first sign of change – A COLD WIND.
