Vanguard (#1)

Next: Ascendant

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 plan: 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…


“Campbell’s skillfully constructed tale keeps a riveting pace, making each character’s personal stakes into fundamental threads woven into a high-energy whole.”

Publishers Weekly, Starred Review

“Sympathetic characters combined with authentic details of military maneuvers on land and in space are the hallmark of a writer still at the top of his form, comparable to authors such as David Drake and David Weber.”


“An imaginative and in-depth novel that spans time and space, VANGUARD will make you want to explore the vast possibilities the universe has to offer.”


“Plenty of high-stakes action and deep-space intrigue that is deftly constructed, consistently surprising and thoroughly engaging.”

“VANGUARD is another winner for me, both as a prequel series and as a fresh start. It’s got that excellent readability that is present in all Campbell’s novels, and when the story is itself engrossing you just can’t lose. VANGUARD also has the added benefit of being a great place for newcomers to join […] In short, highly recommended.”


“Campbell knows how to write military fiction. You never need to fear a lack of action or unrealistic action. His characters are well written and he shows a society that doesn’t just talk a good game related to equality.”


“A near constant stream of space and ground combat keeps the action moving, and the characters are both fun and feel real. Highly recommended for anyone who enjoys space opera, military SF, or even just a deftly written, fast-moving story.”
