Assistant Trader Jethri Gobelyn was an honest, hardworking young man who knew a lot about living onboard his family's space-going trade ship; something about trade, finance, and risk-taking; and a little bit about Liadens. It was, oddly enough, the little bit he knew about Liadens that seemed like it might be enough to make his family's fortune, and his own, too. In short order, however, Jethri Gobelyn was about to find out a lot more about Liadens...like how far they might go to protect their name and reputation. Like the myriad of things one might say-intentionally or not-with a single bow. Like what it would take to make a Liaden trade-ship crew trash a bar. Like how hard it is to say "I'm sorry!" in Liaden. Pretty soon it was clear that as little as he knew about Liadens, he knew far less about himself. With his very existence a threat to the balance of trade, Jethri Gobelyn needed to learn fast, or else help destroy all he held dear.

Red Schuhart is a stalker, one of those young rebels who are compelled, in spite of extreme danger, to venture illegally into the Zone to collect the mysterious artifacts that the alien visitors left scattered around. His life is dominated by the place and the thriving black market in the alien products. But when he and his friend Kirill go into the Zone together to pick up a “full empty,” something goes wrong. And the news he gets from his girlfriend upon his return makes it inevitable that he’ll keep going back to the Zone, again and again, until he finds the answer to all his problems.

Our universe is ruled by physics. Faster than light travel is impossible—until the discovery of The Flow, an extradimensional field available at certain points in space-time, which can take us to other planets around other stars.

Riding The Flow, humanity spreads to innumerable other worlds. Earth is forgotten. A new empire arises, the Interdependency, based on the doctrine that no one human outpost can survive without the others. It’s a hedge against interstellar war—and, for the empire’s rulers, a system of control.

The Flow is eternal—but it’s not static. Just as a river changes course, The Flow changes as well. In rare cases, entire worlds have been cut off from the rest of humanity. When it’s discovered that the entire Flow is moving, possibly separating all human worlds from one another forever, three individuals—a scientist, a starship captain, and the emperox of the Interdependency—must race against time to discover what, if anything, can be salvaged from an interstellar empire on the brink of collapse.

Guy Montag is a fireman. In his world, where television rules and literature is on the brink of extinction, firemen start fires rather than put them out. His job is to destroy the most illegal of commodities, the printed book, along with the houses in which they are hidden.

Montag never questions the destruction and ruin his actions produce, returning each day to his bland life and wife, Mildred, who spends all day with her television 'family'. But then he meets an eccentric young neighbor, Clarisse, who introduces him to a past where people did not live in fear and to a present where one sees the world through the ideas in books instead of the mindless chatter of television.

When Mildred attempts suicide and Clarisse suddenly disappears, Montag begins to question everything he has ever known.

Hailed for his grandeur of imagination and superb worldbuilding, winner of and nominee for more than fifty awards for his outstanding work, Mike Resnick has rightfully won a place as one of science fiction's master storytellers. Now, in Kirinyaga, Resnick presents the haunting and utterly compelling tale of one man's utopia.

By the twentieth second century in the African nation of Kenya, polluted cities sprawl up the flanks of sacred Mount Kirinyaga. Great animal herds are but distant memories. European crops now grow on the sweeping savannas. But Koriba, a distinguished, educated man of Kikuyu ancestry, knows that life was different for his people centuries ago--and he is determined to build a utopian colony, not on earth, but on the terraformed planetoid he proudly names Kirinyaga.

As the mundumugu--witch doctor--Koriba leads the colonists. Reinstating the ancient customs and stringent laws of the Kikuyu people, he alone decides their fate. He must face many challenges to the struggling colony's survival: from a brilliant young girl whose radiant intellect could threaten their traditional ways to the interference of "Maintenance" which holds the power to revoke the colony's charter. All the while, only Koriba--unbeknownst to his people--maintains the computer link to the rest of humanity.

Ironically, the Kirinyaga experiment threatens to collapse--not from violence or greed--but from humankind's insatiable desire for knowledge. The Kikuyu people can no more stand still in time than their planet can stop revolving around its sun.

Deeply moving, swiftly paced, and profound in its implications, Kirinyaga is Mike Resnick's most triumphant work to date. His Fable of Utopia is the book every science fiction reader will want to own and savor for years to come.
