Armchair Fiction presents extra large editions of classic science fiction double novels. The first novel "Danger Moon" is another engaging and highly entertaining tale from a master of science fiction, the late, great Frederik Pohl. Steve Templin had worked as a professional trouble-shooter for years, but now he wanted something different in his life. It wasn't going to be easy, though, and it certainly wasn't going to be cheap. And when Ellen Bishop, owner of Terralune Projects, asked for his help, he agreed... for a price. Something strange was happening to her father's Lunar mining firm and she needed someone like Templin to get to the bottom of it. As he weighed into the situation, he discovered a web of sabotage, greed, and murder-and soon after, the remains of an ancient alien race. The second novel is "The Hidden Universe" by the man who gave us "The Radio Planet," Ralph Milne Farley. Bob Cathcart was happy when his brother, Johnny, had landed a job with the gigantic Frain Corporation. Johnny had signed on and was shipped off to one of Malcolm Frain's secret industrial colonies. But that had been six months earlier, and that was the last time Bob Cathcart had seen or heard from his brother. So with his career as a chemical researcher going nowhere, Bob decided to take a job as a truck driver for the Frain Corporation, partially in hope of finding out what had happened to his missing brother. Like his brother before him, he was also shipped out to one of Malcolm Frain's secret colonies. But after his arrival, it didn't take Bob Cathcart long to discover that the colony he had come to was like no place he had ever seen. In fact, he soon came to the grim realization that this colony might not even be located on Earth!
