Five AI. One mind. Zero mercy.

Technical Specialist Kerry Sevvers commands hundreds of combat drones through the AI cluster in his neural implant, making him the Autonomous Weapons Division's deadliest operator against alien raiders. But his secret weapon is also his greatest crime. Six is an unsanctioned intelligence with no safety protocols, no oversight, and one obsession: finding Sev's mother, taken by raiders sixteen years ago.

Six is illegal. Six is unpredictable. And when everything goes wrong, Six is his only hope.

When a Marine rescue mission uncovers an ancient derelict beyond the frontier, Sev discovers the raiders serve the Concordat—humanity's forgotten nightmare, who transform captured colonists into daxed: cyborg slaves stripped of everything but obedience. As his sanctioned AI fall to alien corruption, Sev must choose: upload Six directly into his neural implant, or watch his team die. But Six wasn't built to follow rules. It was built for revenge.

The Division says unsanctioned AI will destroy humanity. But when your enemy turns humans into weapons, the only way to win is to unleash what they fear most.

Intrusion Protocol launches the Autonomous Weapons Division trilogy, military SF where the battlefield is neural, the enemy is evolution, and the most dangerous weapon is the one inside your head. Perfect for fans of Marko Kloos, James S. A. Corey, and John Scalzi.
