    They called him Charlie. He had big eyes, abundant body hair and fairly long nostrils. His skeletal body was found clad in a bright red spacesuit, hidden in a rocky grave. They didn't know who he was, how he got there, or what had killed him.

    It was a 1961 Hugo Award nominee, losing to Walter M. Miller's A Canticle for Leibowitz. A novella-length version of the story was included in the anthology The Science Fiction Hall of Fame, Volume 2, edited by Ben Bova.Before 1969, every science fiction writer wrote his or her own version of the first Moon landing. Few carry the horror of Budrys' unsettling story.During all recorded history, the Moon has hovered above our heads, a timeless symbol for lovers' ecstasy. Goddesses & Gibson Girls have tripped the light fantastic of her beams while sonneteers & scientists have scanned her changing phases. Now humans had actually reached the Moon, & on it the explorers found a structure, a formation so terrible & incomprehensible that it couldn't even be described in human terms. It was a thing that devoured people; that killed them again & again in torturous, unfathomable ways.Earthbound are the only two men who could probe the thing: Al Barker, a reckless thrill-seeker, whose loving mistress was death, & Dr. Edward Hawks, a scientific murderer, whose greatest mission was rebirth.

    And, the strangest thing of all is everybody believes him.

    Rails must be freshly laid ahead of the city & carefully removed in its wake. Rivers & mountains present nearly insurmountable challenges to the ingenuity of the city's engineers. But if the city does not move, it will fall farther & farther behind the optimum & into the crushing gravitational field that has transformed life on Earth. The only alternative to progress is death. The secret directorate that governs the city makes sure that its inhabitants know nothing of this. Raised in common in creches, nurtured on synthetic food, prevented above all from venturing outside the closed circuit of the city, they're carefully sheltered from the dire necessities that have come to define human existence. Yet the city is in crisis. People are growing restive. The population is dwindling. The rulers know that, for all their efforts, slowly but surely the city is slipping ever farther behind the optimum. Helward Mann is a member of the city's elite. Better than anyone, he knows how tenuous is the city's continued existence. But the world he's about to discover is infinitely stranger than the strange world he believes he knows so well.
