Digital immortality is possible. She knows why it's forbidden.

When brilliant cryptographer and ISTF agent Calla Cress identifies an ancient pattern hidden in Tibetan manuscripts, she unwittingly becomes the key to unlocking humanity's most dangerous discovery: digital immortality.

A secretive scientific coalition led by billionaire tech visionary Tashi Montaigne claims to have perfected the "Eternity Hypothesis" – a revolutionary formula merging quantum computing with ancient consciousness transfer rituals. As the world's elite scramble to control this technology, Calla recognizes something the scientists missed – these aren't just mathematical formulas, but warnings.

From the windswept monasteries of Tibet to the shadowy tombs of Egypt and the mysterious monoliths of Easter Island, Calla and her team, including operative husband Nash Shields and tech genius Jack Kleve, race to decode a global network of consciousness that has been protected by guardians for millennia.

But they aren't alone in this pursuit. Mason Laskfell, a figure Calla believed defeated, manipulates events from the digital shadows, seeking not just immortality but dominion over whose consciousness survives—and whose doesn't.

As quantum disturbances threaten the very fabric of human consciousness worldwide, Calla must confront the ultimate question: Was death designed as our enemy, or our protector?

In this high-stakes international thriller spanning ancient wisdom and bleeding-edge technology, New York Times bestselling author [Author Name] delivers a pulse-pounding adventure that will change how you think about life, death, and what might lie beyond. For fans of James Rollins, Matthew Reilly, and Daniel Silva who crave thought-provoking action that pushes the boundaries of reality.

Immortality was never the gift they promised. It was the trap.
