Search Worlds Without End

During all recorded history, the Moon has hovered above our heads, a timeless symbol for lovers' ecstasy. Goddesses and Gibson Girls have tripped the light fantastic of her beams while sonneteers and scientists have scanned her changing phases.

Now man had actually reached the Moon, and on it the explorers found a structure, a formation so terrible and incomprehensible that it couldn't even be described in human terms. It was a thing that devoured men; that killed them again and again in torturous, unfathomable ways.

Earthbound are the only two men who could probe the thing: Al Barker, a homicidal maniac, whose loving mistress was death, and Dr. Edward Hawks, a scientific murderer, whose greatest mission was rebirth.

Continuing the third in a series of authoritative new editions of the novels of Hugo and Nebula Award-winning author Robert Silverberg. During his heroic first encounter with an alien race, Dick Muller was permanently altered, hideously transformed in a way that left him repulsive to the entire human race. Alone and embittered, he exiled himself to Lemnos, an abandoned planet famed for its labyrinthine horrors, both real and imagined. But now, Earth trembles on the brink of extinction, threatened by another alien species, and only Muller can rescue the planet. Men must enter the murderous maze of Lemnos, find Muller, and convince him to come back. But will the homeless alien, alone in the universe, risk his life to save his race, the race that has utterly rejected him?

In their attitude towards the Planet Earth, the Martians had long been divided into two camps: the Observers, benevolent 'meddlers' in human affairs; and the rebellious Abdicators, who sought the Earth's collapse.

But it wasn't until the extraordinary matter of the Earth-Boy, Angelo Pontevecchio, that the enmity between these two factions came to a definite head.

It started as a contest of wills, waged between two opposing Martians for the soul of a single human child.

And before the end, it threatened all life on both Earth and Mars.
