Rogue Moon [EPUB ebook] 

A Hugo Award Finalist: Humanity struggles to understand a killing labyrinth discovered on the Moon in this science fiction adventure about death and rebirth Hugo and Nebula Award–winning author Robert Silverberg credits Rogue Moon with containing “the most terrifying pages in any SF novel I have ever read.”   A monstrous apparatus has been found on the surface of the moon. It devours and destroys in ways so incomprehensible to humans that a new language has to be invented to describe it and a new kind of thinking to understand it. So far, the human guinea pigs sent there in hopes of unraveling the murderous maze have all died terrible deaths. The most recent volunteer survived but is now on suicide watch. The ideal candidate won’t go insane even as he feels the end approaching. Al Barker has already stared into the face of death; he can handle it again. But he won’t merely endure the trauma of dying. Barker will die over and over—even as his human qualities are preserved on Earth.   With its cast of fascinating characters—like brilliant scientist Edward Hawks, who is obsessed with rebirth—Rogue Moon is a rare thriller that doesn’t just make you sweat. It makes you think.
