"A masterfully orchestrated thriller that spans continents and centuries. Brian Young juggles dual expeditions with precision, building tension through every cave collapse and hostage standoff while never losing sight of the human stakes at the story's heart."

Eighteen months after the destruction of the First Temple, Ammon Lundquist has built something unprecedented: a global coalition of guardians, scholars, and protectors spanning three continents. Two more ancient repositories have been discovered—the Temple of Eastern Waters in the Greek islands and the Temple of Southern Stars in Patagonia. For the first time in millennia, the hidden network is coming together.

But their enemies have been busy too.

Two teams. Two continents. One desperate search.

In the Mediterranean, cyber-security expert Jonas West joins forces with Dr. Yuki Tanaka to infiltrate a remote monastery harboring secrets that powerful forces have killed to protect. Meanwhile, in the wilderness of Patagonia, Aspen Rhoades-Lundquist leads a team into uncharted territory where an indigenous community has guarded forbidden knowledge for generations.

Coordinating both expeditions from Utah, Ammon must navigate a web of encrypted communications and shifting loyalties while watching helplessly as the people he loves face impossible dangers thousands of miles away.

The hunters become the hunted.

A Russian oligarch with limitless resources has been tracking the Alliance's every move. A Vatican operative draws on centuries of institutional patience and intelligence. As these forces converge, both teams find themselves caught between ancient guardians who trust no outsiders and modern predators who will stop at nothing to claim the prize.

With their eighteen-month-old daughter waiting at home, Aspen confronts the hardest question: How much are they willing to sacrifice to protect a legacy that spans continents and millennia?
