What if everything you ever fought for was engineered?

The Immortality Wars series continues with The Pilgrim: Part I, the first book of the thrilling second trilogy and Book IV of the award-winning series from Harvard-educated author and professor A. Keith Carreiro. A gripping Christian science fiction epic for fans of military sci-fi, space opera, and spiritual warfare fiction.

After thinking he dies in combat, a young warrior discovers a shattering truth: the medieval world he knew was never real. It was a human experiment, engineered by a ruthless society over 500 years in the future, designed to create the perfect weapon. Now that weapon has broken free.

It is 2562 Old Earth Time.

A corrupt ruling council on a distant exoplanet has spent centuries running a deadly galactic war whose twelve bases are locked in a ruthless quest for immortality. Scientists, technicians, and power-hungry leaders have manipulated entire realities and one of those realities has just erupted into their own.

Sergeant Pall Warren, battle-hardened, spiritually gifted, and utterly unexpected, steps into the heart of this war. He brings with him the combat power of a medieval warrior, the mortal knowledge gained through centuries of experimentation, and a rare spiritual ability unseen in over 540 years.

Pall is hunted on every front. Human greed wants to possess him. The cold manipulation of scientific curiosity wants to study him. The hunger for religious truth wants to claim him. And the terrifying might of cyborg masters wants to destroy him.

He must fight his way through a theater of galactic combat far beyond anything he has ever witnessed or imagined, a war that stretches across dominions, centuries, and the very boundaries of what it means to be human.

Yet through every peril, across two dominions and two worlds, he is sustained by one constant, the love and prayer of a mysterious and beautiful woman from his former life.

A. Keith Carreiro holds master's and doctoral degrees from Harvard Graduate School of Education and teaches English at Bridgewater State University. He began The Immortality Wars series in 2014 as an epic exploration of faith, human civilization, and the true cost of immortality.

If you love Christian military science fiction, galactic war epics, space opera adventure, and stories where ancient spiritual power meets the far future, The Pilgrim: Part I was written for you.
