Pierson's puppeteers, the aliens who discovered it, are understandably wary of encountering the builders of such an immense structure and have assembled a team of two humans, a mad puppeteer and a kzin, a huge cat-like alien, to explore it. But a crash landing on the vast edifice forces the crew on a desperate and dangerous trek across the Ringworld.

    During its third "apparition" in a remote corner of the galaxy, a trio of Russian cosmonauts approach this enigma and attempt to penetrate its mysteries.

    A rebel inhabits a world where conformity and punctuality are top priorities and the Ticktockman cannot accept the Harlequin's presence in his perfectly ordered world.

    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.

    But what his neighbors must never know is that, inside his unchanging house, he meets with a host of unimaginable friends from the farthest stars.More than a hundred years before, an alien named Ulysses had recruited Enoch as the keeper of Earth's only galactic transfer station. Now, as Enoch studies the progress of Earth and tends the tanks where the aliens appear, the charts he made indicate his world is doomed to destruction. His alien friends can only offer help that seems worse than the dreaded disaster. Then he discovers the horror that lies across the galaxy...

    But even free energy has a price. The transference process itself will eventually lead to the destruction of the Earth's Sun--and of Earth itself.Only a few know the terrifying truth--an outcast Earth scientist, a rebellious alien inhabitant of a dying planet, a lunar-born human intuitionist who senses the imminent annihilation of the Sun.  They know the truth--but who will listen?  They have foreseen the cost of abundant energy--but who will believe?  These few beings, human and alien, hold the key to the Earth's survival.

    He is also an obsessed, driven man determined to murder a rival. To avoid capture, in a society where murderers can be detected even before they commit their crime, is the greatest challenge of his life.

    One of the strangest is on Borthan, where the founding settlers established the Covenant, which teaches that the self is to be despised, and forbids anyone to reveal his innermost thoughts or feelings to another. On Borthan, the filthiest obscenities imaginable are the words "I" and "me." For the heinous crime of "self-baring," apostates have always paid with exile or death, but after his eyes are opened by a visitor from Earth, Kinnall Darival, prince of Salla, risks everything to teach his people the real meaning of being human..

    Enemy Mine--The Nebula and Hugo Award winner that inspired the 20th Century Fox motion picture starring Dennis Quaid and Lou Gossett, Jr.The story of a man, incomplete in himself, taught to be a human by his sworn enemy, an alien being who leaves with the human its most important possession: its future.

    In a way, it's a horror novel tinged with ghastly humor, as the apparently insane ghost of Ernest Hemingway murders a helpless scholar over and over; the scholar slipping from one universe to the next each time he dies, in what is apparently a rather unpleasant form of serial immortality. The tongue-in-cheek explanations for how this could happen qualify the book as a science fiction novel. ... It may be the most 'literary' of my books, but it also has the most explicit sex and the most gruesome violence I've ever written. Nobody will be bored by it."
