Gold the Man

It combines themes of genetic engineering, Cold War politics, and sexuality with an encounter between humans and a race of humanoid giants.

He has built a capsule inside the giant's head, with the ability to control its body's movements from a keyboard while observing the world through one of the eyes.

When Petrovna is killed in an accident on the Moon, the project has to go ahead with his assistant and lover, Marina Syerov, who initially despises Gold.

Flashbacks in the narrative also tell of Gold's upbringing in a research facility, particularly his teenage years when he was found to be sterile despite his strong sexual appetites, and the emotional impact of that discovery.

As the story progresses, Gold comes to appreciate the culture of the giants, as well as discovering that he is not sterile after all, his genetic makeup simply making him slower to mature than humans.
