The Starchild Trilogy

The Reefs of Space brings humanity to the brink of the stars. Steve Ryeland, enslaved by Earth's tyrannical Plan of Man computer, is given the world's most important job: to develop a "jetless drive," an extraordinary new space propulsion mechanism. Yet the most important thing on Steve's mind was not his work, but the iron collar locked securely around his neck. Filled with a lethal charge of explosives, it could be detonated any time the Plan of Man considered him too much of a risk. That's why he had to obey every order & succeed at his experiments. Only then, perhaps, could he use the jetless drive himself…& escape to the safety of the half-mythical Reefs of Space, strange formations rumored to exist somewhere beyond Pluto's orbit. But if he failed, the next step would be the Living Body Bank—a scientific horror chamber from which no one ever returned. (1st published in World of IF Science Fiction magazine, '63)
Starchild stretches even further into the future. Machine Major Boysie Gann has been assigned to duty on Polaris Station, one of the artificial sun-satellites circling near the forbidden reefs. His job: find the Starchild—the source of the mysterious ultimatum calling on the Plan of Man to relinquish its total control over humanity. As proof of his powers, the Starchild has threatened to extinguish the Sun. The awesome fact is—he can actually do it. (1st published as a serial in Galaxy Magazine, '64)
