Helix. The Sentinel Project (en Inglés) - Randy R. Gillespie

When a breakthrough meant to heal the brain becomes a weapon, survival depends on who controls the science.

At a Helix Biotech research facility outside Phoenix, a revolutionary neurological treatment-HX-9-promises regeneration, recovery, and hope. Instead, it unlocks something far more dangerous. When the trial collapses, the dead begin to rise-not mindless, but coordinated, adaptive, and listening.

As the city falls into quarantine, a small group of scientists and survivors race against a military cover-up that's already rewriting the narrative. At the center is Dana Ruiz, a young patient whose body reacts differently to the serum-becoming a living signal the dead can hear.

Hunted by the government, pursued by evolving threats, and forced to confront the cost of their own discoveries, the survivors flee east as the world fractures behind them.

HELIX is a grounded medical-horror thriller about ambition, control, and the terrifying moment when science stops asking should-and starts asking how fast.
