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.
