Billionaire entrepreneur Francis Sandow is the only human ever judged worthy to wield the ancient Pei'an techniques of world creation, for which he has assumed as alter-ego the Pei'an deity Shimbo of Darktree, Shrugger of Thunders. But the Pei'ans have another ancient tradition...of revenge...that will bring Sandow, and his Pei'an rival, unwittingly face to face with an adversary more terrifying than Death itself. One of Zelazny's best.
