Mission Immortal. The Man Who Couldn’t Die (en Inglés) - Janson Davies

They sent him on missions no human could survive.
They never expected him to uncover why.

Captain Steven Colter entered an alien storm against orders-and returned unable to age, bleed, or die.

Galactic Force classifies him as a strategic asset and assigns him to Project Fallen Angel. His orders are simple: go where survival is impossible, complete the mission, and come back alone.

But the battlefields are connected.

Something beyond time is watching through his eyes, mapping humanity one battle at a time. Now a synthetic double and an interdimensional breach stand between the galaxy and invasion.

An unkillable soldier, an alien conspiracy, and a war beyond time collide in this action-packed military science-fiction thriller of immortality, secret experiments, and humanity’s fight for survival.
