An Ace Double with both sides by William F. Temple: Battle on Venus, bound with The Three Suns of Amara. Each side states "2nd printing" and gives dates for original appearance - those dates don't match because each half was originally paired with a different book as Ace Doubles in 1962 or 1963. This pair would make a good introduction to the works of Temple.

Battle on Venus - (Cover by Borgman; 114 pages, copyright 1963.) Expanded from "Field of Battle" in Other Worlds February 1953. Earth's 1st spaceship to Venus landed amidst a war where strange weapons like the archaic ones used in the old wars on Earth in the Twentieth Century hurled shells at each other. But this war had lasted over a thousand years - and by remote control. George Starkey had to find a way to stop the war before the little group of astronauts became early casualties. But how? Where were the headquarters of the contending sides and how do you tell a robot tank that you're neutral? But George had an ally - a Venusian girl who thought stealing was virtuous, and unknowingly, he had something else that turned out to be the most valuable substance on Venus - a box of chocolate bars!

(Bound with) The Three Suns of Amara - Cover by Kelly Freas; 107 pages, copyright 1962.) Retitled from "A Trek to Na-Abiza" in the British continuation of Science Fiction Adventures, July 1961. Alexander Sherret had a journey to make across the surface of Amara, which had everchanging light from the 3 suns. His goal was Na-Abiza - but there was no guarantee it would be there when he arrived.
