Green Odyssey

For two years Alan Green had lived without hope. From the day the spaceship had crashed on this unknown planet he had resigned himself to the destiny created for him by accident and mathematics. Chances against another ship landing within the next hundred years were a million to one. Therefore it would do no good to sit around waiting for rescue. Much as he loathed the idea, he must live the rest of his life here, and he must squeeze as much blood as he could out of this planet-sized turnip.
