An Active Absence

Mateo Rivas is a deep-space salvage operator, drifting through forgotten orbits where no one else dares to go. When he discovers an impossible anomaly-something that exists without mass, energy, or form-his routine mission turns into a nightmare.

The asteroid isn't a rock.

It's alive.

Trapped inside a dying alien intelligence older than humanity, Mateo becomes the unwilling bridge between Earth and something far beyond comprehension. But this isn't an invasion. Not yet.

The entity is not a conqueror.

It is a survivor.

And it needs him.

As reality itself begins to fracture, Mateo uncovers a terrifying truth: the asteroid is not just a creature-it's a lock. And something on the other side is trying to break through.

Now, with time collapsing and no one on Earth believing his story, Mateo must make an impossible choice: help the entity evolve… or risk opening a door humanity may never be able to close.

An Active Absence is a gripping grounded sci-fi thriller about first contact, alien intelligence, cosmic survival, and the fragile boundary between humanity and something far greater.

Perfect for fans of first contact sci-fi, space survival, and philosophical science fiction.
