A World of Difference

When the Viking lander on the planet Minerva was destroyed, sending back one last photo of a strange alien being, scientists on Earth were flabbergasted. And so a joint investigation was launched by the United States and the Soviet Union, the first long-distance manned space mission, and a symbol of the new peace between the two great rivals.

Humankind's first close encounter with extraterrestrials would be history in the making, and the two teams were schooled in diplomacy as well as in science. But nothing prepared them for alien war—especially when the Americans and the Soviets found themselves on opposite sides. . . .
