Machine Major Boysie Gann had been assigned to duty far beyond Pluto, on Polaris Station, one of the artificial sun-satellites protecting the inner planets - and Earth - from the Reefs of Space. For the Starchild had sent an ultimatum to Earth, calling on the Plan of Man to relinquish its total control over humanity under threat of frightful reprisals... and as proof of his powers, the Starchild had threatened to extinguish the sun and a dozen near stars for a period of time.
But Boysie didn't know anything about the Starchild. All he knew was his job - to find out who on Polaris Station was violating the Plan of Man. He found out - and before he could do anything about it, he was captured, marooned on a Reef, and accused of being the Starchild himself! To survive, Boysie had to find out who, or what, the Starchild might be.
And all he knew for sure was that the Starchild did in fact have the power to stop the sun if he wanted to!
