Space Tug by Murray Leinster, paperback

Good condition for a 1955 paperback. Pages are intact with tanning from age. Cover shows much wear but has no tears. 

Synopsis:

Combat Mission! Joe Kenmore's mission was as dangerous as it sounded simple: "Deliver supplies and atomic weapons to the space platform. Then prepare for man's first expedition to the moon."

Joe had helped launch the first Space Platform--that initial rung in man's ladder to the stars. But the enemies who had ruthlessly tried to destroy the space station before it left Earth were still at work. They were plotting to stop Joe's mission!

Bonus: With purchase of this book, you will also receive Space Platform by the same author from 1953, which is in acceptable condition
