Outland — Alan Dean Foster

Here on Lo - moon of Jupiter, hell in space - men mine ore to satisfy the needs of Earth. They are ahrd men, loners for whom the Company provides the necessities: beds, food, drink and women for hire. Now, in apparent suicide or in frenzied madness, the men are dying. To Outland comes the new U.S. Marshal O'Neil, a man with a sense of duty so strong it drives him to ferret out evil, greed and murder regardless of the cost. If he must, he will forfeit love, livelihood - even life itself.
