Man Who Sold the Moon and Orphans of the Sky

Two all-time classics from seven-time Hugo winner and Dean of Science Fiction, Robert A. Heinlein in one volume: The Man Who Sold the Moon and Orphans of the Sky. The Man Who Sold the Moon: D. D. Harriman is a billionaire with a dream: the dream of space for all mankind. The method? Anything that works. Maybe, in fact, Harriman goes too far. But he will give us the stars... Orphans of the Sky: Hugh had been taught that, according to the ancient sacred writings, the Ship was on a voyage to faraway Centaurus. But he also understood that this must be allegory for a voyage to spiritual perfection. After all, the real world was only metal corridors and nothing else, right? And then Hugh begins to suspect the truth. . .
