The trail will lead her back to Tokyo where the thread she pulls threatens to unravel her whole world and bring dark family secrets to light. Meanwhile, the General rises in the East and Emiko must fight the hidden enemies of his growing army who are amped up on Blood Jade, while keeping her promises to her brother Tatsuya as he prepares for his tourney.
