Armchair Fiction presents extra large editions of classic science fiction double novels. The first novel is "Cosmic Junkman," another fine tale by sci-fi stalwart, Rog Phillips. Do Robots dream of playing fetch? Earth's military forces had a unique way of fielding an army. They took the brains of dogs, wiped their memories, and trained them with just the right amount of discipline. Then, they were placed in the bodies of robots that were then used to fight Earth's battles in outer space. What would happen, though, if those dog brains started to regain their memories? What kind of carnage might be released upon humanity if an army of vengeance-seeking robots were loosed upon the Earth? To make matters worse, an alien visitor had exactly that idea-and he had two million robot bodies to help make his invasion plans into reality Here is a taut tale of futuristic espionage, intrigue, and betrayal in this fine novel of an alien invasion. The second novel is "The Ultimate Weapon" by the long-time editor of Astounding Science Fiction, John W. Campbell. The sun Mira had unpredictable cycles. Sometimes it was a searing, brilliant star. But at other times it could also be inexplicably dim and cool, shedding little warmth on the planets of its system. Gresth Gkae, ruler of the Mirans, was seeking a more stable star, one to which Mira's inhabitants could migrate. The new star would have to be stable and have a good planetary system. In his astronomical searching, he found Earth. With an armada of powerful, gigantic spaceships, each well-armed and having light-speed capabilities, the Mirans set out to invade and conquer the Solar System.
