After the brutal ending of the relationship, Kallias reinvents himself in a different household, where he meets and conspires with the cunning and ambitious Julia Agrippina. The emperor's niece has a claim to the throne and the same desires as Kallias: power and revenge at any cost.
Agrippina suggests the schemes and Kallias designs the details. He must risk everything he knows and loves-including his life-in a treacherous hike to reach the top and get even with the man he once worshiped.
