Murray Leinster 
Space Tug 

Though originally geared toward the young adult market, Space Tug, the second novel in Murray Leinster’s Joe Kenmore series, contains enough action and adventure to keep readers of any age engaged. The plot centers on the operation of a space station and is chock-full of the kind of technical details and suspenseful ordeals that fans of golden-era science fiction are sure to appreciate.
