​
Petty Officer Tahir Marcus wanted a routine posting. Instead, he’s stranded on Varissi — a planet consumed by civil war, corruption, and betrayal. When the Alliance command crumbles and insurgents close in, Marcus discovers that the real enemy may be within his own ranks.

Armed with only his instincts, a scarred past, and a secret ability he can barely control, Marcus must navigate gangs, paramilitaries, and double-dealing officers in a desperate bid to survive. Every choice risks exposing him to enemies who want him silenced — or dead.

The Varissian Affair launches The Marcus Files, a military sci-fi thriller series blending gritty survival, galactic intrigue, and high-stakes betrayal. 
Loyalty can hold a crew together — or tear it apart.

After surviving the hell of Varissi, Petty Officer Tahir Marcus finds himself aboard the Thresher, a battered starship assigned to patrol the volatile Disputed Zone. With alliances crumbling and whispers of war spreading across the sector, Marcus soon realizes the ship’s greatest dangers aren’t outside its hull — they’re within it.

The Thresher is failing, its crew divided, and its officers hiding secrets that could ignite a galactic conflict. Caught between duty and survival, Marcus must navigate shifting loyalties, fragile alliances, and betrayals that cut deeper than any enemy fire.

In the Disputed Zone, one wrong decision can doom not only a starship but the fragile peace of entire systems. Marcus must uncover the truth before both the Thresher and his future are lost forever.

The Thresher continues The Marcus Files, a military space opera filled with loyalty, secrets, and survival.
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 caught between warring factions and haunted by memories he can’t escape, even as new pressures threaten to break him.

As alliances fracture and secrets surface, Marcus finds himself tested in ways he never imagined. Shadows from his past, dangerous truths in the present, and the possibility of something more personal than war all collide on a world where the fate of entire systems hangs in the balance.

Rellia Prime delivers the unforgettable finale to The Marcus Files, a military space opera of war, diplomacy, and survival.
