Armchair Fiction presents extra large editions of classic science fiction double novels. The first novel is "The Great Mirror" by Arthur J. Burks. Into the secret heart of Tibet, whence no foreigner had before penetrated, Howard Davies was taken to serve in the strangest conflict ever known. For over not only Tibet, but the entire Earth, hung the menace of Mars and the shadow of a terrible retribution. The Martians wanted their "Great Mirror" back! The Mirror, which had been stolen by the Tibetans, was a seemingly magical device that allowed its users to peer into other worlds or to "transport" themselves to any desired location--anywhere! And when Davies was magically "transported" into the wilds of Tibet, he and his companions soon found they were the only hope for this desperate Himalayan culture. However, time was running out for the Lamas, who were being taken over by the Martian invaders; and in the end, Davies and his comrades had to determine whether the Martians were just trying to teach a lesson to the Tibetans, or reap a bloody vengeance against all of humanity. The second novel, "Terror from the Abyss," is by Sci-Fi author, John Fletcher. As Earth became a sterile, worn-out world, the Bureau of Colonization had sent out hundreds of colonization spaceships, hoping to eventually hear of a world that humanity could flock to. Mankind crossed its fingers and waited. Eventually those ships did find a planet, Nibisia--a green world wrapped with fertile lands, mighty oceans, clean fresh air, and inhabited by friendly humanoid creatures. The settlers from Earth became enthralled with this world, and soon a few of them discovered an even greater secret--the waters of Nibisia had fantastic properties, and when consumed produced enhanced psychic abilities, unimaginable healing powers, and restored youth. But all was not right in paradise, and soon one of Earth's colonists discovered a horrifying secret that could spell doom for any Earthman that set foot on the planet...
