The greatest battles aren't fought with weapons — but with loyalty, betrayal, and power. On Rellia Prime, fragile negotiations promise peace — but every handshake hides a dagger. Petty Officer Tahir Marcus is drawn into a world where alliances fracture, secrets surface, and diplomacy can be just as deadly as war. Haunted by memories of past battles and pressed by forces he can't fully control, Marcus must navigate dangerous truths and shifting loyalties. In a conflict where survival means more than just staying alive, every choice risks igniting disaster. Rellia Prime continues The Marcus Files, a military space opera of war, diplomacy, and survival — perfect for fans of The Expanse, Jack Campbell's Lost Fleet, and John Scalzi's Old Man's War.
