A Reasonable World

Sequel to CV and The Observers. After invading Sea Venture, Earth's largest ocean habitat, the Symbionts have infected the bodies of both humans and animals. Now, people become smarter-or they die. Violence is punished by instant execution from within. But there are those who would turn back the clock-to prevent a reasonable world. 3rd in the CV series from Damon Knight, a SFWA Grand Master.
