A NEW science-fiction action novel about the adventures of our contemporary, who winds up in a barbaric Anti-World and at first receives from the natives the contemptuous nickname “Idiot” for his complete unsuitability for the primitive life there. But our man won’t perish even in the Bronze Age, among half-wild tribes waging endless wars! If you can’t get your way by brute force—use your head. If you weren’t lucky enough to be born a mighty warrior—become a Great Shaman, creating your own people out of refugees and outcasts. If the fate of a “displaced traveler” repels you—be a “progressor,” teach your tribesmen to fight not one by one but in close formation, crush all the neighboring chiefs and petty kings, win the glory of the Invincible. And turn your shameful nickname into an honorable title!
