On the ocean planet Cousteau, humans and dolphins have been genetically altered to dwell permanently in the seas. But now the dolphins are outraged by the damage humans have caused to their environment, and human investigator Galen Yeager and his cyborg partner are sent in to resolve the conflict.
This is a fun story of a secret agent, Galen Yeager, and Sam, his cyborg sidekick. Von Gunden turned his attention from dogs to dolphins for this nice tale with an ecological message. A great beach read!
