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.

To seize the moon from foreign powers--and keep his men alive - Sergeant Ethan Stark must choose which orders to obey - and which to ignore.

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 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.

The Alliance has been fighting the Syndics for a century—and losing badly. Now its fleet is crippled and stranded in enemy territory. Their only hope is a man who’s emerged from a century-long hibernation to find he has been heroically idealized beyond belief… Captain John “Black Jack” Geary’s legendary exploits are known to every schoolchild. Revered for his heroic “last stand” in the early days of the war, he was presumed dead. But a century later, Geary miraculously returns from survival hibernation.

On the world of Dematr, the Emperor and his legions rule over the lands on the eastern side of the Sea of Bakre, and the Great Guilds rule over the Emperor and his subjects. The Mechanics Guild, whose members claim they came from the stars, controls technology far beyond that of the swords and sailing ships of the common people, while the Mage Guild wields strange powers. Jules, an orphan, has fought her way up to become an officer in training with the Emperor’s fleet. But her life is shattered when a Mage prophesizes that her bloodline will one day overthrow the Great Guilds.

For centuries, the two Great Guilds have controlled the world of Dematr. The Mechanics and the Mages have been bitter rivals, agreeing only on the need to keep the world they rule from changing. But now a Storm approaches, one that could sweep away everything that humans have built. Only one person has any chance of uniting enough of the world behind her to stop the Storm, but the Great Guilds and many others will stop at nothing to defeat her.

The world of Dematr had been locked unchanging for centuries by the Great Guilds, most people living in a world of oil lamps, crossbows, and horse cavalry, the Mechanics reserving to themselves the technology for steam locomotives, rifles, and far-talkers while the Mages treated all others as if they were nothing - until Master Mechanic Mari, dragon slayer and pirate queen, and Master of Mages Alain raised the army of the new day to free their world.
