The first book of best-selling sci-fi author Jack Campbell’s new series Beyond the Frontier returns to find Captain John “Black Jack" Geary, the hero of the Lost Fleet series, awoken from cryogenic sleep to take command of the fleet. Geary’s legendary exploits have earned him the adoration of the people—and the enmity of politicians convinced that a living hero can be a very inconvenient thing.

Admiral Geary's First Fleet of the Alliance has survived the journey deep into unexplored interstellar space, a voyage that led to the discovery of new alien species, including a new enemy and a possible ally. Now Geary's mission is to ensure the safety of the Midway Star System, which has revolted against the Syndicate Worlds empire - an empire that is on the brink of collapse.

Geary and the crew of the Dauntless have managed to safely escort important alien representatives to Earth. But before they can make tracks for home, two of Geary’s key lieutenants vanish. The search for his missing men leads Geary on a far-flung chase, ultimately ending at the one spot in space from which all humans have been banned: The moon Europa. Any ship that lands there must stay or be destroyed—leaving Geary to face the most profound moral dilemma of his life.

Two Syndicate World star systems have fallen prey to a mysterious fleet of warships - a fleet controlled entirely by artificial intelligence - that is now targeting Alliance space. The warships are no mystery to Geary. They were developed by his government to ensure security but malfunctioned. If the Syndics learn the truth, the war with the Alliance will resume with a vengeance.

Geary believed in the Alliance. Even when he uncovered overwhelming evidence that the highest echelons of the government and fleet command were involved in secret programs and prison camps, he believed it was worth saving. He believed his duty was to see that justice was served even though some factions feared that revealing the truth would cause the Alliance to crumble. But after narrowly surviving two assassination attempts when he brings evidence of the misdeeds to the capital star system, Geary realizes that some want to get rid of him. 

A legendary hero, he is promoted to fleet admiral—even though the ruling council fears he may stage a military coup. Geary has never fought for the sake of glory. His new rank means only that he has the authority to negotiate with the Syndics, who have suffered tremendous losses and may finally be willing to end the war. With grim determination, Geary leads the fleet back out into Syndic space.

Deep within Syndicate World space, the Alliance fleet continues its dangerous journey home under the command of Captain John “Black Jack” Geary—revived after a century spent in suspended animation. Geary’s victories over the enemy have earned him both the respect—and the envy—of his fellow officers… 

In the three years since former fleet officer Rob Geary and former marine Mele Darcy led improvised forces to repel attacks on the newly settled world of Glenlyon, tensions have only gotten worse. When one of Glenlyon's warships is blown apart trying to break the blockade that has isolated the world from the rest of human-colonized space, only the destroyer Saber remains to defend it from another attack. Geary's decision to take Saber to the nearby star Kosatka to safeguard a diplomatic mission is a risky interpretation of his orders, to say the least.

Following a successful coup, the leaders of the rebel Midway Star System struggle to forge a government free enough to please its citizens yet strong enough to secure power. But in a world where former rulers have become new foes, an alien threat to humanity may turn old adversaries into uncertain allies. General Artur Drakon knows three words describe someone who confides in a Syndicate CEO: Stupid. Betrayed. Dead. Despite his misgivings, he partnered with another former CEO to overthrow Syndic forces.

Geary knows that some political factions in the Alliance were just trying to get rid of him when he was assigned to escort a diplomatic and scientific mission to the far reaches of humanity's expansion into the galaxy . . . and beyond. But he views his mission as both a duty and an opportunity to make things better wherever he can. And when a crippled Rift Federation ship tumbles out of jump space, Geary leaps into action. But the survivors' story isn't completely adding up. As Geary investigates, he finds himself fending off spies and assassins while leading the fleet across space.

The authority of the Syndicate Worlds’ government is crumbling. Civil war and rebellion are breaking out in many star systems, despite the Syndic government’s brutal attempts to suppress disorder. Midway is one of those star systems, and leaders there must decide whether to remain loyal to the old order or fight for something new.

Earth is no longer the center of the universe. After the invention of the faster-than-light jump drive, humanity is rapidly establishing new colonies. But the vast distances of space mean that the old order of protection and interstellar law offered by Earth has ceased to exist. When a nearby world attacks, the new colony of Glenlyon turns to Robert Geary, a young former junior fleet officer, and Mele Darcy, a onetime enlisted marine.

The United Terran Federation is on the brink of collapse after a devastating attack by the Eastern Star Alliance that has left four planets depopulated and uninhabitable. Terrified member worlds are fleeing from the Federation and the remnant of their once-mighty fleet has retreated to the last place they are welcome: Earth. Out of options and time, the Federation turns to Admiral Jackson Wolfe and his new superweapon that could be the key to turning the tide of the war in their favor. Admiral Wolfe knows that no matter what, the fate of humanity will be decided in the coming battle.

After Lieutenant Magnus awakes from the orbital strike that nearly killed him, he discovers that a small contingent of his Marine platoon has also survived. Hope glimmers as he devises a plan to rescue them. But when Magnus learns that his men are being held hostage by a deadly tribe, he fears the worst. Aided by volunteers from a group of elite Marauders, Magnus must attempt to cross the hostile city of Oosafar. Time is running out...and he has no choice but to undertake the most deadly urban assault of his career.

Seeking to escape the shadow of Annette Bond’s success, Captain Morgan Casimir has taken a posting on the far side of the A!Tol Imperium. Here she hopes to begin a legend for herself that stands apart from her stepmother, the Duchess. A chance encounter introduces her to the xenoarchaeologist Rin Dunst - and to the strange mystery cult that tried to silence him. There are darker secrets in these stars than the A!Tol and their human allies ever guessed...and if they can’t find answers, the Precursors' mistakes might yet destroy the galaxy. Again.
