No one had ever penetrated the Great Thorn Forest until Tarzan of the Apes crashed his plane on his first solo flight. Within lay a beautiful country. But in it lived the Alahi, strange stone-age giants whose women regarded all men as less than slaves. And beyond the Alahi lay the country of the Ant-Men – little people only eighteen inches tall. There, in Trohanadalmakus, Tarzan was an honored guest – until he was captured by the warriors of Veltopismakus in one of the ant-men's wars. They had their plans for the ape-man. By the advanced science of the little men, Tarzan was shrunk to their size and set to work as a quarry slave.
