Summary: Brave paladin. Royal princess. Fierce dragon. Simple. Being all three at once? Way too complicated. Paladin Snillek's mother was human and ruled a planet. That's about the extent of her knowledge since they didn't see each other much. When her mom dies in a freak accident, her father tells Snillek she's inherited the title, and she has to learn how to pass as the mostly human Princess Siel for a planet she never thought about much. The dresses alone are horrifying and the courtiers aggravating. ​ In a moment of frustrated rage, Snillek's princess persona slips and frightened palace staff misinterpret what they see. Now Paladin Snillek has been called upon to rescue Princess Siel…from herself. Gruyere wants desperately to journey into the wilds of Tarribotia, but it's too dangerous to go alone and so far, everyone's laughed at her for suggesting it. When she spots a Dzedek paladin sulking in a tavern, she offers her services, hoping to pass herself off as a rogue guide. Two women with secrets and possibly opposing goals head out into the hinterlands of a planet neither one of them knows well. They might both make it back by Winterfest if nothing eats them first. This book contains one out-of-her-element paladin, the perils of academia, deadly cake, and unconventional dragons.

Summary: A vampire hunter has his sights on Anne Perrin, threatening to unleash the very evil she and her friends are fighting to contain. Robbing Anne of her pulse hasn’t stopped her from living un-life to its fullest: she’s balancing two relationships, has returned to her waitress job, and is trying her best to not eat her customers. But Calum sees through her disguise, and no amount of charm can dissuade him from eradicating Anne and everyone like her from the face of the Earth. While Charlie is out of the country seeking help from the one person who might be able to save his life, Anne is abducted, leaving the rest of the Z-Tech crew with the desperate task of finding her before the vampire hunters finish her off — or a grief-stricken Zima destroys the city looking for her lost love. But Anne’s abduction could be just the first part of a larger, darker plan that may unwittingly unleash the very plague Calum seeks to prevent.

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: To escape an arranged marriage, the king needs a fake fiancé. Stat. King Bastien’s father locked him into an ironclad betrothal contract with Lady Helena Rey when the two of them were only seven years old. Bas and Helena have never been friends—and not only because she marked their first meeting by dropping a frog down his shirt. He’s been unsuccessfully petitioning Parliament to annul the damn contract ever since he took the throne nine years ago. But with the deadline for officially confirming the engagement rapidly approaching, Bas is getting desperate. Enter commoner Nico Pereira, manager of the Royal Crest Vineyards, who nurses a secret crush on the king. He’s at the New Palace to unveil a  wine that’s the first joint venture between North and South Abarra. No problem, right? Except Nico has a secret: He has a superpower. Not a very strong superpower, but because powers are a privilege reserved for Royals, it still puts him at risk for arrest and prosecution. Nico can usually mask his limited foresight gift under the guise of being an incredibly efficient administrator. But when King Bastien asks him to be his fake fiancé? Well. Nico never saw that coming. Nothing if not loyal, Nico accepts the faux-posal, although close proximity to Bastien makes him more than a little… uncomfortable, and the increased scrutiny of government officials threatens to expose his illegal ability. Good thing this engagement is temporary, because being the king’s ex will be a lot less onerous than prison or exile. Or, if the attacks from a shadowy conspiracy continue, with being dead. King’s Ex is a 52,000-word M/M superhero rom-com featuring a fake engagement, class differences, improbably pristine clothing, dueling secrets, a guaranteed HEA, and a kitten.

Summary: Rose was waiting tables at Ken’s All-Nite Diner in Keokuk, Iowa, circa 1959, when something happened that would change her life forever. Two men burst through the front door, fighting for their lives. Though it was morning, she could see stars in the nighttime sky through the doorway as the door closed behind them. The larger of the two men quickly gained the advantage, knocking the smaller man unconscious before running out of the diner. Rose, a student nurse, quickly patched up the injured man, and when an ambulance arrived, insisted on riding with him to the hospital. His name was Henry Martin, according to his driver’s license, though both the license and the money in his wallet are dated some 60 years in the future. There’s something else, too—a portable telephone that plays music and seems to have a miniature color television inside. Just who is Henry Martin, where did he get these things, and why is someone trying to kill him?

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.
