STARWOLF #1 - THE WEAPON FROM BEYOND

Artwork by Jack Gaughan, Ace paperback, 1967.

Rear-cover synopsis: 

"Morgan Chane was an Earthman by parentage, but he had been born on the pirate-world Varna, whose heavy gravity had developed strength and incredibly quick reflexes in him. When he was old enough, he joined the raider-ships that looted the starworlds, and fought side by side with the dreaded Starwolves of Varna. But then there was a fight among them. Chane killed their leader, and the other Starwolves turned on him. He barely got away alive - wounded near death, his Starwolf pursuers following him across the galaxy. And there was nowhere he could seek refuge, for no world would lift a hand to save one of the hated Starwolves."

DOOMSTAR

Belmont SF paperback, Jan 1966. Cover artist uncredited.

"The sun shone brightly on this fateful morning, bringing to its planets warmth and life-giving rays. The brightness increased sharply as the morning grew older. The glare was blinding; the radiation not life-giving, but deadly. By mid-afternoon the brilliant, intense sun shone on barren space. It had blasted each of its four planets out of existence. 

Someone had found a way to poison a star. 

And someone had to be found who could prevent the takeover - or destruction - of the entire universe. Who? Johnny Kettrick, as improbably a hero as there never was. Johnny Kettrick was banned from the cluster world for his not-too-honest dealings was sent back there with his three equally unholy partners to search out the doomstar...To find the Doomstar before it burned out another world."
