Grass For His Pillow by Lian Hearn
Takeo, heir to the great Otori clan, has pledged his life to the secret tribe. His supernatural skills of invisibility and acute hearing make him their most deadly assassin. He must deny the spiritual vows of his peaceful upbringing, his birthright of wealth, land and power- and his love for Kaede. If he does not devote himself to the brutal activities of the tribe, they will kill him.
