THE GREKS BRING GIFTS

Madfadden paperback, second printing, February 1968.
Cover artist uncredited.

"THE GREKS WERE PEOPLE-HATERS 

They came to Earth in their space ship, bearing fabulous gifts - such as machines that did any day job automatically, and fertilizer that made plants shoot up overnight. But they presented their gifts with contempt, and with a look in their eyes that made people feel "creepy". 

Still, because of the brave new world they promised, they Greks could be forgiven anything - until they left and people discovered the machines were breaking down. Then their only choice was to beg the Greks to come back, on their own terms. And they knew the terms would be hard..."

SPACE TUG

Belmont SF paperback, Nov 1968. Illustration by Jack Gaughan.

"There had been two attempts to blast it with atomic bombs, but it was aloft now, floating grandly around the earth. - this was the space platform. The crew badly needed food, air, water and means of self-defense. It was up to Joe Kennmore to make the first flight to carry a cargo into outer space; but the opponents of the platform hadn't given up..."

INVADERS OF SPACE

Tandem SF paperback, 1968. Cover artist uncredited.

"Things were quiet that night in the space port. Then the 'Theban' arrived without warning, bringing with it a surly crew, led by a blustering captain, Larson... 

The 'Theban' was old, propelled by a totally obsolescent interplanetary drive. The only way Larson could get it off the ground was to kidnap the young engineer, Horn, who he hoped could at least manage to keep the ship in flight until it reached its final rendezvous. 

Their destination was the spaceship 'Danae' - a ship loaded with millions in space credit notes. If horn wanted to save the 'Danae' from the onslaughts of the Space Invaders, he had his work cut out for him..."

S.O.S. FROM THREE WORLDS

Ace paperback, 1966. Cover painting by Jack Gaughan.

"Virtually the only connecting links between the innumerable colonized planets were the med ships -- lone starships carrying only one man and one beast. These trained teams of super-medical engineers took their lives in their hands on every planetfall. And for the team of Calhoun and Murgatroyd, three calls for help meant three challenges beyond all the experiences of all their systems. Plague, mystery, and menace marked the missions -- and the human enemies they faced on each world were just as virulent as the microscopic ones. Murray Leinster, dean of science-fiction writers, is at his thought provoking best in this exciting space adventure."
