For the first time in paperback, Armchair Fiction presents extra large editions of classic science fiction double novels. The first novel, "Shadow on the Moon" is a futuristic tale of sci-fi espionage and intrigue by Joe Gibson. Imagine gangsters in rocket ships! Man had reached the moon. And now, with scientific technology striding quickly forward, the possibility of consumer rocket ships was at man's fingertips. However, the Earth's most vile dictators and criminals sought to steal top scientific secrets that could threaten the skies and perhaps even the spaceways themselves, casting an ominous shadow on the moon. It was up to a tough World Police Inspector to see that this didn't happen-and when the crisis landed in his lap, he soon found he had far more to worry about than the contemplation of his gorgeous secretary's beautiful legs. The second novel, "Armageddon Earth" is a grim tale of alien invasion and atomic doom by sci-fi veteran, Geoff St. Reynard. At first it seemed like a weird industrial accident when the welder burned his hand off without uttering the slightest whimper of pain. Then someone took a shot at one of Project Star's leading scientists. Soon the men at the project discovered that the flying disks that they were secretly manufacturing for the government weren't exactly as they were first planned. But who was making these changes-and for what purpose? What lay ahead for Earth was a nightmare of carnage beyond human comprehension.
