Summary: Oberon is unique among the Common Worlds - a half-world with a strange past and an uncertain future. Jameson Havercamp and Xander Kinnson are thrust into the middle of a world-ending event and have to scramble to save the world - and themselves. Along the way, they peel back the layers of the onion to discover secrets wrapped in secrets that will eventually take them to where it all started - and may provide the key to saving Oberon and everyone on it. SKYTHANE Jameson Havercamp, a psych from a conservative religious colony, has come to Oberon—unique among the Common Worlds—in search of a rare substance called pith. He’s guided through the wilds on his quest by Xander Kinnson, a handsome, cocky skythane with a troubled past. Neither knows that Oberon is facing imminent destruction. Even as the world starts to fall apart around them, they have no idea what’s coming—or the bond that will develop between them as they race to avert a cataclysm. Together, they will journey to uncover the secrets of this strange and singular world, even as it takes them beyond the bounds of reality itself to discover what truly binds them. LANDER The world needs saving, again. Xander and Jameson thought they’d fulfilled their destiny when they brought the worlds of Oberon and Titania back together, but their short-lived moment of triumph is over. Reunification has thrown the world into chaos. A great storm ravaged Xander's kingdom of Gaelan, leaving the winged skythane people struggling to survive. Their old enemy, Obercorp, is biding its time, waiting to strike. And to the north, a dangerous new adversary gathers strength, while an unexpected ally awaits them. In the midst of it all, Xander’s ex Alix returns, and Xander and Jameson discover that their love for each other may have been drug-induced. Are they truly destined for each other, or is what they feel artificial? And can they face an even greater challenge when their world needs them most? ITHANI Time is running out. After saving the world twice, Xander, Jameson and friends plunge headlong into a new crisis. The ithani―the aliens who broke the world―have reawakened from their hundred millennia-long slumber. When Xander and Jameson disappear in a flash, an already fractured world is thrown into chaos. The ithani plans, laid a hundred thousand years before, are finally coming to pass, and they threaten all life on Erro. Venin and Alix go on a desperate search for their missing and find more than they bargained for. And Quince, Robin and Jessa discover a secret as old as the skythane themselves. Will alien technology, unexpected help from the distant past, destiny and some good old-fashioned firepower be enough to defeat an enemy with the ability to split a world? The final battle of the epic science fiction adventure that began in Skythane will decide the fate of lander and skythane alike. And in the north, the ithani rise….

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.

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: An Imperial prince can only hide for so long—but his solution of a hastily invented engagement could backfire spectacularly. Marsh Kensinger's work as the utility mechanic for Bremen Station keeps his life interesting - but never quite as interesting as finding a pilot still hidden inside a hibernation drawer in what should have been a salvage craft. He knows he shouldn't get involved, but the Altairian Imperial crest on the private craft and the semi-conscious pilot's odd questions pique his always-whirling curiosity. Still unattached at a concerning age for an imperial son, Prince Shiro Shinohara hadn't been running from the endless, mind-numbing rounds of omiai his mother, the Empress, had mandated. Not exactly. He'd just wanted a break from persistent suitors at the family retreat on Ceti Tau. The short respite becomes a panicked flight for his life when one of the suitors stalking him attacks the family compound. Worried for the soldiers he was forced to leave behind, afraid there's a conspiracy to kidnap him, Shiro confides in the handsome mechanic who found him and in a moment of panic, concocts the fiction of a serious relationship with Marsh. It's only until Shiro's people can reach him and he can press charges back home. Marsh is willing to play along and Shiro's just going to have to keep himself together and not, under any circumstances, fall for the wonderful, generous man who refuses to stop helping him.
