Armchair fiction presents extra large paperback editions of the best in classic science fiction novels. "The Sunken World" written by Stanton A. Coblentz, is a wonderful science fiction undersea thriller. It was the launching of a new, futuristic submarine, the mighty X-111. But the country was shocked when its Captain and crew were reported lost at sea shortly after launch. It was an abrupt ending to a maiden voyage that had started so promisingly. However, it was only the beginning, the beginning of an underwater adventure never before heard of or imagined by the land-dwelling peoples of Earth. Keep company with the men and women of a truly remarkable underwater city, whose existence in our history has only been noted as rumor-or myth. This is Stanton A. Coblentz's epic tale of Atlantis...the lost continent of old, described as no other author before him.
