The Thresher: A Marcus Files Novel — A Space Opera of Loyalty and Secrets

by Jonathan Kuiper, Virtual Voice (Narrator)

A broken ship. A fragile alliance. And a captain who can’t afford another mistake.

After surviving Varissi, Petty Officer Tahir Marcus should have been done with war. Instead, he’s assigned to the Thresher—an aging starship limping through the Disputed Zone, where every border skirmish threatens to ignite into galactic war.

But Marcus soon learns the Thresher isn’t just falling apart — it’s filled with secrets. Officers hide agendas, alliances shift with every whisper, and one wrong decision could shatter what little trust remains among the crew.

As loyalty and betrayal collide, Marcus must decide who he can trust before both the ship and his future are destroyed.

The Thresher continues The Marcus Files, a space opera of loyalty, secrets, and survival — perfect for fans of The Expanse, Jack Campbell’s Lost Fleet, and John Scalzi’s Old Man’s War.
