Two classic Robert A. Heinlein novels in one volume, with an all-new introduction by Mark L. Van Name, author of the Jon and Lobo military SF series. D. D. Harriman is a billionaire with a dream: the dream of space for all mankind. The method? Maybe, in fact, Harriman goes too far. But he will give us the stars... 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. . . Two all-time classics from seven-time Hugo winner and Dean of Science Fiction, Robert A. Heinlein. “Not only America's premier writer of speculative fiction, but the greatest writer of such fiction in the world.” –Stephen King. “One of the grand masters of science fiction.” – Comprehensive Teacher's Guide available.
