The experiment was meant to heal. Instead, it created something unstoppable.

For eighty-four years, Project Joy failed to accelerate human regeneration. Every subject died—until a convicted murderer survived.

Thomas Evers didn’t walk out of that lab human. Something ancient woke in his blood, fusing forbidden biotechnology with a power that should never have touched this world.

Now the scientist who saved him finds herself guiding a man caught between evolution and extinction. A man the military wants as a weapon. A man a shadow cult sees as a prophecy. A man a ruthless billionaire intends to control at any cost.

As alliances fracture and old powers stir, Dr. Charli Stanwick faces a single impossible truth:

If Thomas loses control, humanity will fall. If she loses him, the last hope of a better world dies with him.

R4G3 is a science-fantasy thriller where genetic engineering collides with ancient power—perfect for fans of monster-evolution thrillers, conspiracies, and dark fantasy.
