Summary: Lida was their last chance for an uncolonized planet. But a world-spanning fungus had colonized it first. Agetha and her husband have spent their whole lives in the fleet’s zero-G. Now all is turmoil as the fleet lands, discovering they are surrounded by a single fungal biomass spanning the entire planet. To build a new home, the fleet must confront a dangerous organism, and Agetha must decide if she can raise a family in this inhospitable landscape. Jane Brighton holds tenuous command over the colony and its administrators. She and the other gene-modded leaders emerged from their four-hundred-year suspended animation to find a crew much different from the one that departed Old Earth. Jane must direct the colony’s fragile growth and defend it against being overrun by the fast-growing biomass. But there is something none of the colonists know. The massive organism that spans the planet is not simply a fungal mass, nor even a chimerical combination of species that once roamed the planet. The biomass has desires and goals, and one is to know these strange beings carving out a home in its midst. Download today to read of the colony’s fate in Of Mycelium and Men!

Summary: Nothing is new under another sun. Not even murder. This mission should be simple. Exoplanetary scout Leif Grettison and ace pilot Yang Yong are off to deliver a load of supplies and reinforcing settlers to a recently colonized planet. It’s as routine as a starflight can be. Famous last words. Something is wrong with the colonists. They are astonishingly ill-suited for the task of settling a new world. The planet, too, is a poor place to plant a town for humans. Even if everything goes right, the colony might not survive. Then one of the colonists is found dead. Murder is a possibility. Not long after, another one dies—and this time, it’s definitely murder. In a world with only two hundred people, there’s at least one killer. Meanwhile, the colony’s new leader has a plan—but Leif has doubts. Will this man save the settlement, or use his power to become a dictator? Leif and Yong’s mission is clear: they must leave the colony in shape to survive. Leif is a retired soldier, not a detective, and when it comes to investigating a crime, he doesn’t have a clue. Literally. Still, it falls to him to follow the evidence and find the killer. He also needs to deal with the leader and the leader’s plan. If Leif fails, the only mystery may be how long it will take for everyone to die.

Summary: Life after the Crash. Over a century after the end of the Earth, life goes on in Redemption, the sole remaining Lunar colony, and possibly the last outpost of humankind in the Solar System. But with an existential threat burrowing its way into the Moon's core, humanity must recolonize the homeworld. Twenty brave dropnauts set off on a mission to explore the empty planet. Four of them—Rai, Hera, Ghost and Tien—have trained for two-and-a-half years for the Return. They're bound for Martinez Base, just outside the Old Earth city of San Francisco. But what awaits them there will turn their assumptions upside down—and in the process, either save or destroy what's left of humanity.

With her world locked in a battle against rising seas, scientists deploy genetically modified corals to rebuild reefs and protect the coastline.

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?
