I also have this book with a red cover, but am keeping both in my PC.

From the back cover of this 1978 reprint:

"LUKE SKYWALKER FOUGHT THE FORCES OF AN EVIL SPACE-TYRANT. ON HIS DARING MISSION A FORCE OF LIFE BECAME THE POWER OF DEATH!

Luke Skywalker was bored with farm chores. He wanted adventure out among the stars. He wanted to see the wonders of other worlds.

But Luke got more than he expected when he discovered a mysterious message from a beautiful princess who was being held prisoner by an evil, powerful warlord of space. Luke didn't know who she was. But he knew he had to save her before time ran out.

Armed only with courage and the amazing light-sword that had once been his father's, Luke soon found himself in the middle of the greatest space-war ever. And he was headed straight for a desperate fight...on the monster enemy battle station called the Death Star!

A GREAT SPECTACULAR FROM 20TH CENTURY FOX

THE GREATEST FILM OF THE CENTURY!"
