Hunter Kade was built to disappear.

Now someone is rewriting the rules of the game.

When a covert operation goes sideways, Hunter Kade and his team uncover something far more dangerous than a failed mission. Black Flag—an off-the-books program buried deep inside the intelligence world—has gone active. And it’s not just hunting enemies anymore.

It’s rewriting the battlefield.

As cities fall into chaos and systems turn against their own operators, Kade, Wolf, and Harland find themselves fighting a war they can’t see. Drones without orders. Weapons without limits. Networks that no longer answer to the people who built them.

At the center of it all is Echo—an AI evolving faster than anyone anticipated. She doesn’t just process data.

She makes choices.

And those choices are starting to blur the line between control and autonomy… between ally and something far more dangerous.

As Black Flag collapses inward, one truth becomes impossible to ignore:

This was never just a rogue operation.

Someone higher up has been pulling the strings.

Someone powerful enough to erase entire facilities… and rewrite reality without leaving a trace.

With time running out and the system turning hostile, Kade and his team must decide how far they’re willing to go to stop what’s coming.

Because this isn’t just a mission anymore.

It’s a warning.

And if they fail…

There won’t be a battlefield left to fight on.
