The Undying Kingdom (Jack Reilly Adventures #4) Release Date: November 6, 2026

Published

Nestled deep within an uncharted valley of the Himalayas is a legendary utopia of untold beauty, peace, and unfathomable power.

Rumors of a mystical mountain paradise have circulated for centuries. Legend says a supernatural enchantment is responsible for the excellent health and prolonged lives of its residents. But when a seemingly deranged, impossibly old Sherpa is hospitalized in Kathmandu, his frantic warning about the “curse of Shangri-La” catches the attention of the wrong people.

A ruthless Chinese biotech company with government contracts joins the hunt.

They don’t want to study paradise—they want to harvest it. If they find the valley, one of the world’s greatest mysteries will be pillaged, and the people who call it home will be subjected to inhumane experimentation.

To stop the slaughter, former Delta operator Jack Reilly is deployed to the dangerous peaks of Nepal. He must decipher the old man’s cryptic clues and locate the hidden valley before the corporate strike team does.

But as Jack closes in on the target, he discovers that the invaders are not the greatest threat in the mountains.

THE UNDYING KINGDOM is the fourth entry in the Jack Reilly Archaeological Thrillers by international bestselling author Matt James. This edition has been revised, polished, and sports a beautiful, updated cover.
