Sinopsis

Cyborg IV is a science fiction/secret agent novel by Martin Caidin that was first published in 1975. It was the fourth and final book in a series of novels Caidin began in 1972 with Cyborg, profiling the adventures of astronaut Steve Austin, who becomes a spy for the American government after an accident that requires the replacement of numerous body parts with high-powered machines.

In Cyborg IV, Caidin takes the notion of cyborg to new extremes as Steve Austin's consciousness is hooked up to a next generation spacecraft, creating a new form of union between man and machine. Meanwhile, an enemy force plans to use similar technology for their own ends.
