When a neurological breakthrough meant to save lives becomes the spark of a nationwide catastrophe, the line between cure and weapon disappears. As the dead begin to move—not as monsters, but as remnants of a corrupted experiment—scientists, soldiers, and survivors are forced to confront a terrifying truth: this outbreak was engineered, concealed, and allowed to spread in the name of control. At the center of it all stands Dr. Mackenzee Roth, a brilliant neurologist whose life’s work was twisted into something unrecognizable. As the cost of her discovery becomes impossible to ignore, Roth and her team must race against time to stop a system that no longer answers to reason, compassion, or restraint. HELIX: THE SENTINEL PROJECT is a grounded, emotionally charged science thriller about responsibility, sacrifice, and the devastating consequences of believing that the end always justifies the means. Some cures don’t heal. Some systems don’t forgive. And some mistakes demand more than survival to be set right.
