Humanity thought it was alone. It was wrong.
When Commander Kael Voss intercepts a mysterious signal from beyond explored space, he unknowingly uncovers the greatest secret in human history. Entire star systems have vanished from the official records. Ancient battles have been erased. And an invisible enemy has been watching civilization for centuries.
As colony worlds fall one by one and the Galactic Alliance suffers devastating defeats, Kael discovers that the war humanity is fighting is far older than anyone imagined. Hidden beneath forgotten military installations lies the truth behind the Echo Protocol-a conspiracy that buried humanity's past to protect its future.
With civilization on the brink of extinction, Kael must unite divided governments, distrustful allies, and even former enemies against an unstoppable force that adapts to every strategy.
But the greatest threat is not the alien fleet destroying worlds.
It is the ancient power awakening beyond the edge of known space.
As impossible choices demand impossible sacrifices, Kael must decide whether humanity's future can be saved without becoming the very thing it fears.
Military Echoes is an epic military science fiction adventure filled with colossal space battles, tactical fleet warfare, ancient mysteries, political intrigue, and unforgettable heroes. Perfect for fans of The Expanse, The Lost Fleet, Halo, Mass Effect, and Old Man's War.
