Raiders of Gor (The Chronicles of Counter-Earth Volume 6)

"Tarl Cabot was a warrior of Gor - the world that Earth could never see. Normally, he was a proud and mighty warrior. But now he was bound for Port Kar, the only city with no home stone to give it a heart. It was a city of reavers and looters ... of outcasts without allegiance. Merchants and pirates stalked its quays beside the beautiful Sea of Thassa.
