From The Publisher:

The daughter of a samurai never weeps. But Takiko, whose warrior father was killed in battle, finds this a hard rule, especially when her mother remarries a strange and ugly country potter. To get away from her miserable home, Takiko eagerly accepts a position at the imperial Japanese court. There, her beauty and nightingale voice captivate the handsome young warrior, Hideo -- who also turns out to be an enemy spy. As war breaks out, Takiko flees the court and is forced to choose between loyalty to her people and her love for Hideo. She painfully learns that whatever choice she makes, she cannot run away from her samurai honor.
