    This is the story of a lie that became the most powerful kind of truth. A timeless novel as urgently compelling as War Day or Alas, Babylon, David Brin's The Postman is the dramatically moving saga of a man who rekindled the spirit of America through the power of a dream, from a modern master of science fiction.He was a survivor--a wanderer who traded tales for food and shelter in the dark and savage aftermath of a devastating war. Fate touches him one chill winter's day when he borrows the jacket of a long-dead postal worker to protect himself from the cold. The old, worn uniform still has power as a symbol of hope, and with it he begins to weave his greatest tale, of a nation on the road to recovery.

    Strange fireballs race through the sky above the deepest trenches of the oceans. Something is about to show itself, something terrible and alien, a force capable of causing global catastrophe.

    The Stars My Destination is a classic of technological prophecy and timeless narrative enchantment by an acknowledged master of science fiction.

    When famous adventurer Sir Richard Francis Burton dies, the last thing he expects to do is awaken naked on a foreign planet along the shores of a seemingly endless river. But that's where Burton and billions of other humans (plus a few nonhumans) find themselves as the epic Riverworld saga begins. It seems that all of Earthly humanity has been resurrected on the planet, each with an indestructible container that provides three meals a day, cigarettes, alcoholic beverages, a lighter, and the odd tube of lipstick. But why? And by whom? That's what Burton and a handful of fellow adventurers are determined to discover as they construct a boat and set out in search of the river's source, thought to be millions of miles away. Although there are many hardships during the journey--including an encounter with the infamous Hermann Goring--Burton's resolve to complete his quest is strengthened by a visit from the Mysterious Stranger, a being who claims to be a renegade within the very group that created the Riverworld. The stranger tells Burton that he must make it to the river's headwaters, along with a dozen others the Stranger has selected, to help stop an evil experiment at the end of which humanity will simply be allowed to die. --Craig E.

    NASA, NATO, and the UN sent explorers to the asteroid's surface...and discovered marvels and mysteries to drive researchers mad.For the Stone was from space--but perhaps not our space; it came from the future-but perhaps not our future; and within the hollowed asteroid was Thistledown.

But while scientists and politicians bickered about how to use the information to stop the Death, the Stone yielded a secret that made even Earth's survival pale into insignificance.
