About the book
New York Times Notable Book of the Year
Explore a universe where genetic mutations allow individuals to traverse the stars in this action-packed space opera for fans of Frank Herbert and Samuel R. Delaney!
It is the second stage of human colonization—the first age, humanity’s initial attempt to people the stars, ended in disaster when it was discovered that Earth’s original superluminal drive did permanent genetic damage to all who used it—mutating Earth’s far-flung colonists in mind and body.
Now, one of Earth’s first colonies has given humanity back the stars, but at a high price—a monopoly over all human commerce. And when a satellite in Earth’s outer orbit is viciously attacked by corporate raiders, an unusual young woman flees to a ship bound for the Up-and-Out.
But her narrow escape does not mean safety. For speeding across the galaxy pursued by ruthless, but unknown adversaries, this young woman will discover a secret which is buried deep inside her psyche—a revelation the universe may not be ready to face . . .

About the book
Carson Flint left the Commonwealth's wars behind for the quiet life of running a saloon on the edge of nowhere.
The Bulwark sits on Castus, the last neutral ground in a galaxy that tore itself apart. Smugglers, refugees, and war-weary soldiers drift through its doors, and Carson keeps his corner of it calm by staying out of everyone else's business.
Then a dying man stumbles in carrying a secret worth killing for.
The stranger came out of Commonwealth service, hunted across the stars, holding something the Thortan warlords will level a settlement to reclaim. When their guns reach Castus, neutrality means nothing, and the Bulwark stands between a ruthless militia and a discovery that could reshape a galaxy.
Carson only wanted a quiet life. But some doors, once opened, pull you toward the adventure of a lifetime.

About the book
A high-velocity fusion of techno-thriller and first-contact sci‑fi.
In this explosive third novel in Paul McGrath’s award-winning Terran Incognita Series, Russian disinformation masterminds and a ruthless Texas tech billionaire are about to unleash a “data vacuum cleaner” that can rip through the world’s financial systems—and hand Moscow unprecedented power. Deep underground in Virginia, a vanished prisoner suddenly reappears in a different body, forcing the FBI to reopen the most bizarre case in its history. And at the center of it all are two off-the-books Xylodonian Guardians, hiding in plain sight as a small-town Mississippi couple, quietly using alien tech to freeze militias, topple traffickers, and derail mass killers before they strike.
As FBI agents start connecting impossible events—from a sex-slave compound in Idaho to a congressional hearing where everyone mysteriously “stopped”—the hunters and the hunted are set on a collision course that spans West Texas bunkers, St. Petersburg troll farms, and secret bases far beyond Earth.
Smart, sharp, and almost plausible, A Hard Left delivers cutting-edge cyber intrigue, dark humor, and near-future thrills with a cosmic twist.

About the book
When the Jedi Order falls, an Inquisitor rises.
Padawan Iskat Akaris has dedicated her life to traveling the galaxy alongside her master, learning the ways of the Force to become a good Jedi. Despite Iskat’s dedication, peace and control have remained elusive, and with each setback, she feels her fellow Jedi grow more distrustful of her. Already uncertain about her future in the Jedi Order, Iskat faces tragedy when her master is killed and the Clone Wars engulf the galaxy in chaos.
Now a general on the front lines contributing to that chaos, she is often reminded: Trust in your training. Trust in the wisdom of the Council. Trust in the Force. Yet as the shadows of doubt take hold, Iskat begins to ask questions that no Jedi is supposed to ask. Questions about her own unknown past. Questions the Jedi Masters would consider dangerous.
As the years pass and the war endures, Iskat’s faith in the Jedi wanes. If they would grant her more freedom, she is certain she could do more to protect the galaxy. If they would trust her with more knowledge, she could finally cast aside the shadows that have begun to consume her. When the Jedi Order finally falls, Iskat seizes the chance to forge a path of her own. She embraces the salvation of Order 66.
As an Inquisitor, Iskat finds the freedom she has always craved: to question, to want. And with each strike of her red blade, Iskat moves closer to claiming her new destiny in the Force—whatever the cost.

About the book
Henry Morgan went to a baseball game hoping to catch a pop fly - not an untimely death from a flying lawnmower to the head.
It's the lawnmower he gets. But he doesn't stay dead. Instead, he wakes up to find that a century has passed, and he's being drafted to be the governing AI for humanity's first interstellar starship.
In the year 2117, humanity is confronted by a metastasizing alien threat that's already established itself in the asteroid belt.
It's Henry the starship's job to sail out to it, investigate it, and end it.
Or to die trying.

Our take
Fourteen-year-old prodigy Ethan Cole buys an old Apple II and discovers the vanished research of a Cold War physicist whose unsanctioned project could reshape modern physics.

About the book
At the end of the Cold War, a physicist at Oak Ridge National Laboratory was pursuing an unsanctioned project that could reshape modern physics. Then he vanished — his lab seized, his research classified, his name erased from the record.
Thirty-five years later, Ethan Cole — fourteen years old, a prodigy, more capable than engineers twice his age — purchases the physicist's old Apple II at an estate sale. Inside, he finds hand-built hardware, encrypted disks, and notebooks full of equations thought to have disappeared with the physicist. The work was revolutionary and ahead of its time. Decades ahead.
Fully realizing the physicist's vision wasn't possible with 1980s technology. But three decades of advancement have closed the gap — and Ethan has the skills to finish what was started. The question is whether he should. The last person who tried never came home.
Sometimes going back is the only way forward.
