Vintage 192 page mass market paperback titled DEATHWORLD 3 by Harry Harrison/ A Dell Book # 1849, First Printing, May 1968 / Deathworld is the name of a series of science fiction novels by American writer Harry Harrison, including the books Deathworld (first published 1960, serialized in Astounding Science Fiction), Deathworld 2 (1964, initially titled The Ethical Engineer and serialized in Analog) and Deathworld 3 (1968, serialized in Analog as The Horse Barbarians), plus the short story "The Mothballed Spaceship" (1973, written as part of a tribute to John W. Campbell). The central hero is a gambler who becomes involved with colonists of an extremely hostile planet. In Deathworld 3, Jason invites those Pyrrans who cannot adapt to the changes on their home world to colonize "Felicity", a planet rich in mineral wealth, but home to humans who are divided into two primitive societies, reminiscent of early Asia. One is an agrarian society living in towns and cities; the other is composed of nomadic clans that constantly fight amongst each other, strongly reminiscent of the Mongols before they invaded China and settled down. The two are divided by an impassible, miles-high, continent-spanning cliff. Most of the warlike clans have recently been united under a wily leader calling himself Temujin. Jason tries to infiltrate the warrior society and use his Pyrrans to wrestle the leadership of the clans away from Temujin, but is unmasked as an off-worlder and thrown down a deep cave. He survives the fall, landing in a bank of snow and finds that it is a passageway through the cliff. Jason changes his plans and contacts Temujin, who takes him for an unkillable demon. Jason offers the barbarian leader his greatest wish, to conquer the rest of the continent. Temujin does indeed prove unstoppable, but is perceptive enough to realize, at the peak of his triumph, that he has to pay an enormous price for what he has won, as his people are becoming corrupted by the easy life of civilization and will forget their nomadic ways. The book is complete and in VERY GOOD or better condition with some overall wear. The edges of the insides of the front and back covers are browning and the inside pages are tanned.
