The Planet Savers
Author: Marion Zimmer Bradley
 
The Planet Darkover was threatened by a deadly epidemic that would destroy both Terran and Darkovan civilisations. The only known cure lay somewhere in the vast wastelands of Trailman territory.
One man alone could lead them there. Jason Allison - raised by the semi-human Trailmen.
And only one man could develop the cure - parasitologist Dr. Jay Allison, a neurotic genius who refused to leave his hospital.
The clashing personalities of the two men are at war - the two brilliant minds are in one man's body. Can the Planet ever be saved?
