You never prize anything so much as when you feel you're about to lose it. So you fight to preserve it, and when you've done that you've built up enough excess energy to want to make a stab at something better. And when that's threatened you'll fight again and so on until the final curtain. It's just the way things are.

There was trouble brewing on Mars--_bad_ trouble. Two giant industrial empires fought for control there, and their struggle imperiled the whole Mars colony. Civil war--atomic civil war--could break out any second, leaving Earth's only foothold in Space a mass of radio-active rubble. But both antagonists were too politically powerful for the Colonization Board to take a direct hand. One man was needed to take charge--one man who could act fast and decisively, brutally if he had to. Ralph Graham got the job. And then people began dying around him.... In MARS IS MY DESTINATION, veteran author Frank Long spins a fast suspense story in the classic tradition of "action" science-fiction--a story of Tomorrow and a crisis in the advance into Space.
