Immune to pain, invincible in combat... all America would one day fear the masked warriors of the Tengu... In Japanese mythology, the TENGU is the most terrible of all demons: a living force of evil that infects its followers with the mad strength of the berserk and the capacity to survive attack from any weapon... At the close of World War II, the TENGU was Japan's most terrifying secret weapon. Now the demon is unleashed again - this time in a diabolical plot to wreak vengeance on America for the mega-destruction of Hiroshima... Steeped in the sinister magic of ancient Japan and rich in exotic sensuality, Tengu is a terrifying novel of nuclear revenge - and Graham Masterton's most stunningly horrific thriller to date.
