Armchair fiction presents extra-large paperback editions of the best in classic science fiction novels. “Space Tug” by sci-fi master Murray Leinster is another space opera adventure featuring Joe Kenmore, the hero of Leinster’s prequel, “Space Platform” (also available from Armchair Fiction). There were only 30 minutes to live! Joe Kenmore heard the airlock close with a sickening wheeze and then a clank. In desperation he turned toward Haney. "My God, we've been locked out!" Through the transparent domes of their space helmets, Joe could see a look of horror and disbelief pass across Haney's face. But it was true! Joe and his crew were locked out of the Space Platform. Four thousand miles below circled the Earth. Under Joe's feet rested the solid steel hull of his home in outer space. But without tools there was no hope of getting back inside. Joe looked at his oxygen meter. It registered thirty minutes to live. “Space Tug” is the exciting sequel to Murray Leinster’s “Space Platform,” which is also available in an Armchair Fiction edition.
