"Yamada no Goji is a minor nobleman of ancient Japan who has lost everything--except a single purpose: keep a promise to the woman he loved. In order to fulfill his vow, all he has to do is fight a horde of demons and monsters, bargain with a few ghosts, outwit the sinister schemers of the emperor's court, find a way to defeat an assassin who cannot be seen, heard, or touched--and change the course of history. Fortunately, Yamada specializes in achieving the seemingly impossible, so he is sure in some way to succeed...if he doesn't drink himself into oblivion first"--Page 4 of cover.
