Servants of the Wankh. Marooned on Tschai, Adam Reith agreed to lead an expedition to return the princess Ylin Ylan, the Flower of Cath, to her homeland halfway around the globe. Monsters of land and sea lay before them, and beings both human and alien who might rob, kill or enslave them. Tschai was a large and ancient planet, where 4 powerful alien races struggled for mastery while humans were treated like pawns. But the girl's father was enormously wealthy, her homeland technologically sophisticated. If Reith was ever to obtain human aid in returning to Earth, where better than Cath? But after traveling lands controlled by the Chash, he had to deal with the Wankh. The Wankhmen were cold as ghouls, and it was not wise to cross them.
