Commander Julián Peralta is dying, and he knows it. Fifteen years after a comet wiped out Earth, he's been holding together what's left of humanity from a drifting space station while a neurological plague slowly destroys his mind.

Then something impossible appears - a gateway to a parallel universe where the comet never happened, where Earth is still alive.

With nothing left to lose, he volunteers for a one-way mission: send his consciousness across, find his other self, and stop the disaster before it begins. A last shot at saving humanity.

But the man he meets isn't a hero. He's already in control, already building a world that looks perfect on the surface… and wrong underneath.

What follows is a quiet war between two versions of the same mind, unfolding across realities, while something unseen watches from behind it all.

A high-concept science fiction thriller blending parallel universe, consciousness transfer, and AI dystopia, Double Blind explores how far we're willing to go to survive-and what we might lose along the way.
