The Fox Protocol: Constant

By: J S Cross

Your body is not your own. Your mind was built by someone else. And the man who designed you wants you back.

Julian Cross can dismantle a billionaire's empire before breakfast. A corporate negotiator trained to read micro-expressions, he controls every room he enters - until a woman with his exact face walks into the lobby of the Langham and hands him a thirty-year-old medical prototype with his initials etched into the back.

She tells him his insulin pump has been hacked. That his glucose levels have been monitored since he was a child. That the man he called "Father" didn't just raise him - he calibrated him.

Now Julian must follow a trail of breadcrumbs through a secret network of conditioned subjects scattered across Europe: a painter who sees futures she cannot change, a translator with gills who has been dreaming inside the Danube for decades, a sister who might be his twin or his assassin, and a seventeen-year-old boy still holding a door open inside a dead network.

At the heart of the conspiracy lies the Ark - a mountain laboratory where Father is preparing the final harvest. Seven souls. One vessel. Immortality on his own terms. Julian has been engineered to be the constant, the unchanging baseline against which all others are measured. But constants can break. And when they do, the whole equation burns.

The fox has been running for twenty-one years. The door is open. Walk through it.

The Fox Protocol: Constant is a razor-sharp psychological thriller with the emotional depth of a literary novel and the propulsive tension of the best conspiracy fiction. Perfect for fans of Blake Crouch's Dark Matter, Alex Michaelides' The Silent Patient, and the layered storytelling of Stranger Things.
