A renegade martial arts Sensei known as the Tengu has been recruited to train a splinter group of Asian terrorists with links to Al Qaeda. The Tengu mourns the vanished prestige and cultural heritage of Imperial Japan. He, like the men he trains, believes the West is responsible for destroying the spiritual essence of a once-great culture. Connor Burke and his martial arts teacher Yamashita are pawns in a game that will ensnare them while they search for the most deadly of foes: the Tengu.
