Desert Viper: A Stiller–Sawyer Story (The Lost Tomb series Book 11)

Arizona, 1970. In the uneasy shadow of Apollo 13, NASA pilot Cameron Sawyer is pulled off course by an anomaly only high-altitude reconnaissance has ever recorded: a flawless geometric rectangle cut into the Sonoran sand—too precise to be natural, too old to be man-made, and aligned with a compass that should not matter in a place like this.

He isn’t the first to notice.

Cameron comes from a bloodline known for finding what should stay hidden—doors (portals) that open where the world insists there are only walls. For a century, the Espejo Foundation has been waiting for someone like him to look in the wrong direction at exactly the right time.

They send their answer.

A woman marked by a feathered serpent inked into her skin. A reputation that precedes her as a warning whispered too late. La Víbora. The Viper. She doesn’t hunt quickly. She hunts completely.

What Cameron uncovers in the desert is not a ruin. It is an aperture—something sealed by civilizations that understood what lay beyond it. Not a tomb, but a passage. And on the other side is something that does not feed on the dead.

It keeps the living.

To survive, Cameron will have to accept the one inheritance he has spent his entire life outrunning—and decide whether the stories his family carried were warnings… or instructions.

Because some doors don’t stay buried.

And the desert never forgets what was opened.

Perfect for readers of James Rollins, Douglas Preston & Lincoln Child, and Steve Berry—an archaeological thriller with a supernatural edge, following a bloodline of door-finders across a world that was never meant to stay closed.
