And then…

    For aeons this golden-skinned, golden-eyed race had provided the universe mercenary soldiers of almost unimaginable ability. But now the mri have faced an enemy unlike any other - an enemy whose only way of war is widespread destruction. These "humans" are mass fighters, creatures of the herd, and the mri have been slaughtered like animals.Now, in the aftermath of war, the mri face extinction. It will be up to three individuals to save whatever remains of this devastated race: a warrior - one of the last survivors of his kind; a priestess of this honorable people; and a lone human - a man sworn to aid the enemy of his own kind. Can they retrace the galaxy-wide path of this nomadic race back through millennia to reclaim the ancient world which first gave them life?

    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.

    Delany's 1976 SF novel, originally published as Triton, takes us on a tour of a utopian society at war with . . . our own Earth! High wit in this future comedy of manners allows Delany to question gender roles and sexual expectations at a level that, 20 years after it was written, still make it a coruscating portrait of the happily reasonable man, Bron Helstrom -- an immigrant to the embattled world of Triton, whose troubles become more and more complex, till there is nothing left for him to do but become a woman. Against a background of high adventure, this minuet of a novel dances from the farthest limits of the solar system to Earth's own Outer Mongolia. Alternately funny and moving, it is a wide-ranging tale in which character after character turns out not to be what he -- or she -- seems.

    Although this is the event she has long dreamed of—for her laran is so strong that she has been able to use it without benefit of training or the need of a matrix crystal—and she yearns for the power which will come to her if she succeeds in becoming a Keeper, she is deeply disturbed. For she is plagued by a terrifying premonition that haunts her days and disrupts her nights, the inescapable feeling that something is about to happen—something monumental and dangerous which will descend upon her world and change it utterly. And all she knows for certain is that this something will be coming from one of Darkover’s four moons…

    This naturally brings him in contact with the house full of students and layabouts next door, including a young woman who, in a moment of stress, reveals to him that she has wings--wings, moreover, which grow back after each attempt to cut them off. Alan understands. He himself has a secret or two. His father is a mountain; his mother is a washing machine; and among his brothers are a set of Russian nesting dolls. Now two of the three nesting dolls, Edward and Frederick, are on his doorstep--well on their way to starvation, because their innermost member, George, has vanished. It appears that yet another brother, Davey, who Alan and his other siblings killed years ago, may have returned...bent on revenge.Under such circumstances it seems only reasonable for Alan to involve himself with a visionary scheme to blanket Toronto with free wireless Internet connectivity, a conspiracy spearheaded by a brilliant technopunk who builds miracles of hardware from parts scavenged from the city's dumpsters. But Alan's past won't leave him alone--and Davey is only one of the powers gunning for him and all his friends.

    He peddled drugs when they were available, carried cargo when they weren't. But he was also the last of the Centaurans - or at least, half of him was - which meant that he was the only person who could operate the Centauri Device, a sentient bomb which might hold the key to settling a vicious space war.Cover illustration: Chris Moore

    So how is it that, in competition with the worst villains the universe has to offer, he's become the proud owner of the last seedship of Earth's legendary Ecological Engineering Corps? Never mind, just be thankful that the most powerful weapon in human space is in good hands-hands which now control cellular material for thousands of outlandish creatures. With his unique equipment, Tuf is set to tackle the problems human settlers have created in colonizing far-flung worlds: hosts of hostile monsters, a population hooked on procreation, a dictator who unleashes plagues to get his own way...and in every case the only thing that stands between the colonists and disaster is Tuf's ingenuity - and his reputation as an honest dealer in a universe of rogues...Tuf Voyaging features interior illustrations by Janet Aulisio. Included in it will be her original eight illustrations, along with 28 newly commissioned ones.
