"Kenji wrote 'The Book of Prophecy' in his boyhood. Now this childish fantasy has become the scenario for the Friend's fiendish plot to destroy mankind. Kenji goes underground and waits for a chance to fight back. Meanwhile, the evil organization is closing in on a man called Shogun in the ganglands of Bangkok. The mystery grows deeper, the fear more intense, as we near the final battle at the turn of the century-- Is there really any way to save the world from annihilation?"--Publisher's web site.
