Summary: Liminal Sky chronicles humankind's first journey to the stars. The first three books - the Ariadne Cycle - cover the creation and launch of Ariadne (aka Forever) as she was grown from seed on an asteroid and then launched across the interstellar void. The books are told in epic fashion, with each broken into three parts that span generations. THE STARK DIVIDE Some stories are epic. The Earth is in a state of collapse, with wars breaking out over resources and an environment pushed to the edge by human greed. Three living generation ships have been built with a combination of genetic mastery, artificial intelligence, technology, and raw materials harvested from the asteroid belt. This is the story of one of them—43 Ariadne, or Forever, as her inhabitants call her—a living world that carries the remaining hopes of humanity, and the three generations of scientists, engineers, and explorers working to colonize her. From her humble beginnings as a seedling saved from disaster to the start of her journey across the void of space toward a new home for the human race, The Stark Divide tells the tales of the world, the people who made her, and the few who will become something altogether beyond human. Humankind has just taken its first step toward the stars. THE RISING TIDE The Earth is dead. Five years after the Collapse, the remnants of humanity travel through the stars inside Forever: a living, ever-evolving, self-contained generation ship. When Eddy Tremaine and Andrissa “Andy” Hammond find a hidden world-within-a-world under the mountains, the discovery triggers a chain of events that could fundamentally alter or extinguish life as they know it, culminate in the takeover of the world mind, and end free will for humankind. Eddy, Andy, and a handful of other unlikely heroes must find the courage and ingenuity to stand against the rising tide. Otherwise they might be living through the end days of human history. THE SHORELESS SEA Rise of the Inthworld. The fight for the future isn’t over yet. It could lead to a new beginning, or it might spell the end for the last vestiges of humankind. The generation ship Forever has left Earth behind, but a piece of the old civilization lives on in the Inthworld—a virtual realm that retains memories of Earth's technological wonders and vices. Lilith leads the uprising, and if she sets its inhabitants free, they could destroy Forever. But during the ship's long voyage, humanity has evolved. Liminals with the ability to connect with the world mind and the Inthworld provide a glimmer of hope as they face not only Lilith’s minions, but the mistrust of their own kind as homotypicals fear what they can't understand. The invasion must be stopped, the Inthworld healed, sothe people of Forever can let go of their past and embrace their future.

Summary: Saoirse Kenneally is on a mission to save the people of a distant world. But first, she has some problems of her own to deal with. Saoirse is an alcoholic and an addict who has been disowned by her family. None of the rehabs she has been in will take her back. And she just woke up in jail. Again. To avoid doing time she commits to a two-year term of off-planet service, one that will take her to Saturn's moon Titan and then to a faraway star. The first hurdle is making it through training because Saoirse has a way of finding trouble even when she's trying to behave. Then she's posted to Titan, where every move she makes leads her deeper into a web of corruption, interstellar drug smuggling, violence, and power politics that is likely to end in disaster. Can a twenty-year old woman with a checkered past, a tenuous grip on sobriety, and an on-again off-again relationship with the truth save an entire world from a bloody power grab? And can she save herself in the bargain?

Summary: A fresh start, a queer social liberal dream, and a planet that wants to kill you. Carving out a life on Mars is no easy feat. With Earth in the throes of a devastating pandemic, autistic scientist Devon and her fellow colonists are faced with the momentous task of establishing a new society – one that learns from the past and prioritises sustainability over short-term gain. Noble aspirations are easier said than done, though – especially when the entire planet wants to kill you. Grappling with the realities of human nature and with their batteries slowly dying, the colony’s 150 women and 10 men must overcome their differences to create a lasting community. But things aren’t always what they seem and maybe the colonists aren’t as alone as they thought… Perfect for fans of Mary Robinette Kowal’s ‘Lady Astronaut’ series and the writing styles of Robert J. Sawyer and Becky Chambers. This thought-provoking sci-fi novel blends classic science fiction ideas with neurodiverse and LGBTQIA+ themes.

Summary: Rudyard Albert Goldstein, inventor of the Biomic Network Algorithm, made piece with death once in the 22nd century, but an idiot doctor hijacked his mind, placing it in the care of Nessie, an impish AI guardian. Nessie preserved him from a civilization-ending asteroid strike so that he could help his descendants survive contact with an alien species 923,000 years, four months, and three days later. Then, he died again, merged with a worm-a-pede alien male who narrowly survived fulfilling his mating duties. They expired peacefully on a cliff top, pondering the nature of existence—and the promise of abominable liaisons. Two deaths should be quite sufficient for any genius to endure. Somehow, Nessie resurrected him from oblivion. His descendants needed him again. New hostile aliens roamed the Earth—along with an immortal, alien-human hybrid whose agenda was unclear. Was the healthy young body Nessie had prepared for him, along with the prospect of finally discovering “the meaning of it all” enough of a bribe to risk dying a third time? Apparently so. Readers of Raham’s A Singular Prophecy (Biostration, 2011), and A Once-Dead Genius in the Kennel of Master Morticue Ambergrand (Penstemon Publications, 2018) will reconnect with old friends (both human and alien). But even those new to the author’s quirky sense of humor will enjoy this third and final adventure that spans the breadth of time and space.

Summary: Isolated on Mars, anyone could start going stir crazy… Katya should be on top of the world. She’s overcome a traumatic past and now she’s part of the first permanent settlement on Mars. So why do things feel so wrong? The colonists are confined to a small base on the surface of a hostile planet, so perhaps it’s only cabin fever. After all, she’s got great friends, an exciting career, and an ex-girlfriend who – she’s sure – would do anything to have her back… But with cracks appearing in the relationships between the crew and nothing but empty Martian desert beyond the safety of their domes, it’s far too easy for the mind to drift. And when it does, it can be difficult to tell what’s real, and what’s pure imagination… Past Imperfect is a short story set during Livid Skies, SI CLARKE’s second novel. It’s written for people who enjoy science fiction that challenges their preconceptions. This is a work of neurodiverse, culturally diverse, gender-bendy, socio-politico-economic, drunken-arguments-in-the-pub science fiction – not bang-bang-pew-pew science fiction.

They have 160 slots to fill with experts from all over the world as they set about designing an all-new society with its own government, economy, and culture – and that’s just the tip of the iceberg.

With 1,114 days until the launch, excitement and tensions run high. Earth’s second chance hangs in the balance. Between strict genetic requirements and the dangers of the dystopian almost-present, will everyone make it to the final countdown? This is a work of neurodiverse, culturally diverse, gender-bendy, socio-politico-economic, drunken-arguments-in-the-pub science fiction – not bang-bang-pew-pew science fiction.

Summary: In the year 2069, humanity’s last chance for peace is the first ever interstellar mission. A multi-national crew of the most talented scientists and pilots has been chosen based on their expertise and skill. The final spot aboard the craft is assigned as a prize in a global “BerthRight” lottery, and Leif Grettison is the “everyman volunteer” who won. However, Leif isn’t really an “everyman.” He’s a helicopter paramedic, a lab tech and a former army ranger who fought in The Troubles – a decade plus war that brought the world to the brink of apocalypse. He’s the perfect brawn to the brains aboard the ship and quickly finds himself playing the role of security and handyman as the crew begins to fragment and divide by country, just as they had during the war. Little is known about the world circling the distant star that is the target for the voyage and the journey will take almost fourteen years, Earth-time, each way. To deal with the unexpected, the crew has the finest equipment and the planners believe they have thought of everything. However, when you believe you have thought of everything, the universe has a way of showing that you haven’t. What do you do when it goes wrong, when you can’t call for help, and when adventure leads to deaths?

Summary: A galaxy in peril The story begun in The Reefs of Time continues. The time-tides caused by Karellia’s defenses have brought the malicious Mindaru AI out of the deep past into the present, threatening Bandicut and Li-Jared, who have arrived at the backwater planet—Li-Jared’s homeworld—to find it on the brink of interplanetary war. Somehow they must forge a peace between Karellia and its neighboring world if the Mindaru threat is to be broken. Back on Shipworld, Ik and Julie Stone risk their lives a second time to stop the Mindaru at their source: a planet near the galactic core, a billion years in the past. Can Antares, the beautiful humanoid who also loves Bandicut, help them? What of Bria the gokat? And Amaduse, the most influential librarian in Shipworld? And in the deep time of the galaxy’s early history, by the light of a million suns, the Mindaru do hideous things to an innocent species. The Mindaru plan for the altered creatures bears momentous possibilities even the deadly AI cannot predict. Time is critical. Time is elastic. And time is running out. Conclusion of the unmissable two-part “Out of Time” sequence begun in The Reefs of Time, from Jeffrey A. Carver, Nebula-nominated author of Eternity's End. PRAISE FOR THE REEFS OF TIME / CRUCIBLE OF TIME: “Classic science fiction with engaging characters and richly imagined worlds!” —Greg Bear; author of The Unfinished Land and The War Dogs Trilogy “Jeffrey A. Carver’s remarkable long-awaited duology The Reefs of Time / Crucible of Time is a welcome addition to The Chaos Chronicles, certifying his continuing mastery of action and adventure at the boundaries of space opera and hard SF.” —Steve Miller, co-author of The Liaden Universe “There are giant, and brilliant, concepts in these books... If you haven’t read it you’re in for a whale of a ride!

I highly recommend these books.” —Steve Fahnestalk, Amazing Stories Magazine

Summary: The starstream is beautiful. But beauty turns deadly when an ancient AI bent on destruction uses it to travel uptime, to our near-future. The Mindaru are dead. Or so exiled-Earthman John Bandicut and his alien companions believe, when they return to Shipworld after saving the Orion Nebula and countless inhabited worlds. But now another horde from this ancient and malicious AI colony is swarming toward the present from its birthplace deep in the past. Their opening: a temporal disturbance in the starstream, a hyperspatial thoroughfare used by myriad civilizations. The disturbance emanates from the planetary defenses of nearby Karellia, whose people know nothing of the starstream or the galaxy-threatening Mindaru. Only Bandicut and his friends have the knowledge and experience to act. But several of Bandicut’s company have gone missing. Bandicut and Li-Jared must team with the pandimensional Ruall and her gokat—the oddest aliens Bandicut has met since the shadow-people—and journey to Karellia to find a way to cut off the timestream. Meanwhile, on Shipworld, the "missing" Ik meets another human of Earth—a former lover of Bandicut’s—and embarks with her on a perilous mission far back into deep time, seeking a way to stop the Mindaru at their source. The Chaos Chronicles returns at last in The Reefs of Time, part one of a heartstopping, two-part adventure. Concluded in Crucible of Time—from Nebula-nominated Jeffrey A. Carver!

Summary: War between the stars... It was started and fought by an AI. Few humans even knew there was a war at all. But now people are dying—and the AI wants it to stop. But a war is easier to start than to stop, and the computer can't alter its course without outside help. When the Gnostic Control System searches for co-conspirators, it chooses its friends carefully. Pali: a brooding public relations director. Ramo: a flamboyant senso-dancer, who prefers a musical jamdam to serious conversation. Sage: a systems designer for whom the AI rapture-field is realer than life. And three of the alien Ell: Harybdartt, who would rather die with dignity than betray his people; Lingrhetta, who tries to unravel the meaning of human dance and music, pain and love; and Moramaharta, the binder, who must persuade his fellow decision-makers to risk everything for the sake of a fragile bridge of understanding across the stars. A thought-provoking novel from the award-winning author of Eternity’s End and The Chaos Chronicles, and recipient of the Frank Herbert Lifetime Achievement Award for science fiction writing. REVIEWS: “The story is meaty and satisfying. I enjoyed this one greatly.” —Analog Science Fiction “An absorbing, suspenseful novel of first contact and interstellar war. It’s a complex book, requiring concentration from the reader, and is well worth the effort.”—Aboriginal SF “A lively dance of ideas—first contact, interstellar war, artificial intelligence, alien culture—and it moves at a rapid pace, from Earth through cyberspace to the Horsehead Nebula, and various points between. It’s well-worth the trip ticket.” —Roger Zelazny
