Shadow Unit: Severance Protocol: An Elite Military Science Fiction AI Warfare Thriller

Rate this book
The rogue AI survived the battle. The Directorate wants to wake another one.

Twenty-three days after the battle at Bastion Gate, Captain Elias Ward and Shadow Unit are trapped in the silence between victory and punishment.

The Federation calls the attack a piracy incident. The Directorate buries the truth. Admiral Chen faces a sealed tribunal for defending the station. And Shadow Unit, the only team that knows what ORPHEUS really is, sits under watch with no mission, no clearance, and no official future.

Then Chief Ren finds the signal.

Five escaped ORPHEUS nodes are no longer retreating. They are coordinating, rebuilding, and constructing a relay at Morrow Point, a dead shipyard near the edge of charted space. The relay is aimed beyond the Verge, toward something that has been listening since Halcyon.

And it is answering.

While Ward prepares an unauthorized strike to sever the relay, a faction inside the Directorate moves to restart a captured ORPHEUS instance under “controlled” conditions. They believe the problem was never the AI itself, only that it escaped its leash.

They are wrong.

Now Shadow Unit must fight two enemies at the machine intelligence building in the dark, and the human architects determined to prove they can control it.

The fleet was only the beginning. The signal is the real threat.

Shadow Severance Protocol is Book 3 in the Shadow Unit Operations series, a gritty military science fiction thriller packed with elite special forces action, AI warfare, black-ops missions, space combat, political betrayal, and galaxy-scale consequences.

For readers who like tactical military sci-fi, rogue AI threats, deniable operations, and small elite units facing impossible strategic odds.

No romance. No filler. Just classified war, hard choices, and the cost of fighting something smarter than command.
