Jack Campbell returns to the world of the New York Times bestselling Lost Fleet novels with a new action-packed military science fiction series that explores the founding of the Alliance . . . and the men and women who fought to create it. 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. With nothing but improvised weapons and a few volunteers, Geary and Darcy must face down warships and armored soldiers—or die trying. As battles rage and pirates take an increasing toll throughout the colonies, the only hope for lasting peace lies with Carmen Ochoa, a “Red” from the anarchic world of Mars, and Lochan Nakamura, a failed politician. They have a to lay the groundwork for mutual defense that could someday grow into an alliance. But if their efforts don’t succeed, the growing power of aggressor worlds could turn regions of space founded on freedom into battlefields between the first interstellar empires...

A young fleet officer and a Marine stand together to defend their colony in the continuation of the powerful and action-packed Genesis Fleet saga from New York Times bestselling author Jack Campbell. In the three years since former fleet officer Rob Geary and former Marine Mele Darcy led improvised forces to repel attacks on the world of Glenlyon, Old Earth and the Old Colonies have continued to shrink their military forces. But open warfare erupts once again when Glenlyon tries to force open a trade route. Isolated and alone, Glenlyon places its hope in informal agreements with other worlds also facing attack. But fiercely independent worlds settled by people who wanted to escape higher authority don’t easily agree to such commitments. While politicians try to bring some kind of formal alliance into being, Geary and Darcy once again find themselves fighting desperately to defend their world, hoping they can hold out until help arrives. If it comes at all.

A young fleet officer and a Marine must stand together to defend their neighbors and their colony in this return to the powerful and action-packed Genesis Fleet saga from New York Times bestselling author Jack Campbell. The recently colonized world of Glenlyon has learned that they're stronger when they stand with other star systems than they are on their own. But after helping their neighbor Kosatka against an invasion, Glenlyon has become a target. The aggressive star systems plan to neutralize Glenlyon before striking again. An attack is launched against Glenlyon's orbital facility with forces too powerful for fleet officer Rob Geary to counter using their sole remaining destroyer, Saber. Mele Darcy's Marines must repel repeated assaults while their hacker tries to get into the enemy systems to give Saber a fighting chance. To survive, Glenlyon needs more firepower, and the only source for that is their neighbor Kosatka or other star systems that have so far remained neutral. But Kosatka is still battling the remnants of the invasion forces on its own world, and if it sends its only remaining warship to help will be left undefended against another invasion. While Carmen Ochoa fights for the freedom of Kosatka, Lochan Nakamura must survive assassins as he tries to convince other worlds to join a seemingly hopeless struggle. As star systems founded by people seeking freedom and autonomy, will Kosatka, Glenlyon and others be able to overcome deep suspicions of surrendering any authority to others? Will the free star systems stand together in a new Alliance, or fall alone?
