Marauders of Gor

Tarl Cabot's efforts to free himself from the directive of the mysterious Priest-Kings of Earth's orbital counterpart were confronted by frightening reality when horror from the northland finally struck directly at him.
Somewhere in the harsh lands of transplanted Norsemen was the first foothold of the alien Others. Somewhere up there was one such who waited for Tarl. Somewhere up there was Tarl's confrontation with his real destiny - was he to remain a rich merchant-slaver of Port Kar or become again a defender of two worlds against cosmic enslavement.
Marauders of Gor is one of the truly great adventures of the Gorean saga. It brings in barbaric peoples, vivid adventure, fierce aliens, and the clash of male-female emotions stripped of civilized pretension that has made John Norman the best-selling writer of high fantasy adventure.
