Yamada Monogatari: The Emperor in Shadow

Lord Yamada is called away-one last time-from his newly restored estates in Kamakura to help Prince Kanemore ensure that Princess Teiko's son, Takahito, inherits the Chrysanthemum Throne. Unfortunately, assuming the throne proves to be the easy part. Yamada must then help Takahito renounce that throne in such a way as to hobble the power of the Fujiwara clan forever!
