Zero, Nyx, and the other Pathfinder colonists have adjusted to life on Kaguya. But Earth has built much faster starships-the Dreamcatcher arrives 10 years early, and the Stargazer arrives so early it actually got there before the Pathfinder did! Now the Stargazer is a lost shipwreck, and the race is on to find it, and who should show up looking for it but Nyx's dangerous family: Big Mama, Jim, and Kratt. Nyx and Zero will face kidnappers, pirates, shipwrecks, warlords, dragons, and maybe a new ally or two on their way to save the day once again.

Heather Kilgore is the deadliest assassin in the Fringe, a fearsome agent for her King and star nation. But when a high-profile defector is found dead outside the embassy on a contested world, Heather is pulled back into a past she'd tried to forget. Her orders are simple: find out why her name was in the dead man's pocket. But nothing is simple in a galaxy of shifting loyalties and buried truths.

After two decades of learning at the Nexus, the children of Van and his crew are ready to take their first steps out in the big black. Aboard their new ship, the AnaDarko, the young officers begin unraveling a mystery that goes beyond the depths of time—where did Gabby's people come from, and why does life, scattered across the gas giants, all sound so familiar to her? Under the capable guidance of Rab, a seasoned Peacemaker, the young crew pursues science and knowledge—even as Van and Torina push back against a threat that originates on earth itself.

The mission is simple. Escort an emissary to an intergalactic peace summit. Try not to get in the way. Lt. Magnus and his 79th Recon Team have certainly handled worse, after all. But when an explosion rocks the tower and sends everyone into a panic, Magnus and his asset find themselves cut off from the rest of the team. Worse still, a dying alien chieftain gives them a priceless drive of intel, marking them for death. The mission has officially changed. With enemies on all sides, Magnus must do everything in his power to protect the emissary and escape the tower.

Earth has fallen under the influence of the Fermion Party, whose members believe humanity’s future lies in the metaverse, a simulated environment to which people can upload their consciousness to become immortal. As a simulant, one cannot get sick, grow old, or die. Human beings have no business risking their lives in the betaverse, where injury and illness can kill them. And those who wish to explore beyond the solar system blaspheme what the Fermions believe is the natural order.

A century ago, the Sentience Wars tore the galaxy apart and nearly ended the entire concept of intelligent space-faring life. In the aftermath, a curious tradition was invented - something to cheer up everyone who was left and bring the shattered worlds together in the spirit of peace, unity, and understanding. Once every cycle, the civilizations gather for the Metagalactic Grand Prix - part gladiatorial contest, part beauty pageant, part concert extravaganza, and part continuation of the wars of the past.

For the King’s best assassin, failure is never an option. But when the head of her Order sends her on an impossible mission, Heather Kilgore begins to question everything she knows. And she’ll have to make a choice: Start a war or fail her mission.

Over the past few decades, a handful of scientists have been racing to explain a disturbing aspect of our universe: only four percent of it consists of the matter that makes up you, me, our books, and every star and planet. The rest is completely unknown. Richard Panek tells the dramatic story of the quest to find this “dark” matter and an even more bizarre substance called “dark energy”. This is perhaps the greatest mystery in all of science, and solving it will bring fame, funding, and certainly a Nobel Prize.

Brad Mendoza is an idiot. He knows it, and so does everyone else. A promising naval career down the drain just, because he accidentally killed 504 civilians. So, it's time for him to give up and accept a dead-end command on Persephone, the worst ship in the fleet. Until he meets the beautiful and cunning Jessica Lin, his new executive officer, who harbors a terrible secret of her own. Now, he's in a race to save her and his stupid ship.

Pursued by a relentless assassin, Alan and Jinny race across the galaxy in search of a secret truth that has eluded humanity for centuries. The 47 colonies have been at peace for over 700 years. But nothing is as it seems. The Council government of all humanity controls the populace through lies, fear, and genetically-engineered agents who do its terrible bidding.

Abducted off the space station where I teach the standard galactic language, I'm imprisoned with two other women in a cold, dirty cell on an alien ship. We're destined for something worse than death until a fierce, blue-haired alien male rescues us. We recover on his ship with his group of Heveian pirates. There, the attraction that formed when he first carried me in his arms grows into a force neither of us can deny. But something else has taken up residence on the ship. Something that will stop at nothing to destroy us all.

Jessica Lin is missing! And Brad Mendoza has no idea where she is. But he has other problems, like the people trying to extort him into capturing a man he was probably going to kill anyway! Now, with bounty hunters, crime lords, their own Navy, and some random gunslinger after them, can Brad and Jessica find a little more dumb luck and save each other and their crew? Old villains return, and new friends are forged as they scramble against the worst odds they've ever seen.

Ryland Grace is the sole survivor on a desperate, last-chance mission - and if he fails, humanity and the Earth itself will perish. Except that right now, he doesn't know that. He can't even remember his own name, let alone the nature of his assignment or how to complete it. All he knows is that he's been asleep for a very, very long time. And he's just been awakened to find himself millions of miles from home, with nothing but two corpses for company.

He finally escaped the cycle of war and death only to find himself kidnapped, taken to a new universe where nothing makes sense. A world where nothing is familiar and insane robots, killer AI, and otherworldly beings he can hardly comprehend are the norm. He must learn to survive these constant threats to his very survival, all the while learning that these new experiences are changing him, molding him into something new...something extraordinary.

I need a deal to survive. But all I have to offer is . . . myself. On the station, humans are the lowest of the low. We take whatever jobs we can, scraping just to get by. Comfort is rare. Security a dream. And a real friend? Almost unheard of. So when my best friend goes missing, I'm desperate to find her. But before long my search leads me to the claws of the leader of the Vinduthi cartel. He's terrifying. Utterly ruthless. He'll help me find my friend, but can I pay the price he demands?

A Russian dissident, a Jesuit priest, and an American mule skinner are but a few of the bold visionaries who crafted the scientific story of cosmic origins. The collective insights of these and numerous creative thinkers advanced human understanding from mythology to mathematics, yielding falsifiable alternatives to ancient folklore and campfire tales. Listening to the Big Bang tells the dramatic human story—filled with colorful characters, unsung catalysts, and glorified heroes—which made the Big Bang the leading cosmological theory.

It seemed the unthinkable had happened. Someone had actually targeted the Ghalian, an order of assassins known and feared across the systems. It was madness. Only a fool would go after the likes of them. But, it seemed, the galaxy had no shortage of fools. Retaliation most bloody was in order, and one man stood ready to spring into action. Hozark was his name, and he was no ordinary man. He was a Master Ghalian, an assassin skilled in the ways of death. Practical, mechanical, magical, to him it made no difference.

To save her people, she will destroy everything. An exciting sci-fi assassin and heist thriller set thousands of years in the future, in a time when humanity has spread through the stars. Everyone wants Heather Kilgore dead, even those she once called friends. Pursued by her own agency, she flees to the Outer Rim, where she’ll attempt one last time to put an end to a war that will kill billions. Her target: an interstellar arms manufacturer bent on destabilizing the Fringe and Heather’s star nation for profit. But she won’t be able to do it alone.
