High in the Andes, buried beneath centuries of stone and myth, lies a forgotten power that was never meant to be found. Elias Kane and Nadia Selim follow the trail of the Atlas Cipher to a temple unlike anything on Earth—alive with ancient technology and pulsing with danger. But they're not the only ones closing in. A resurrected enemy, a former mentor turned zealot, and a countdown buried in the stars all point to one truth: the Cipher doesn't lead to treasure... it leads to a choice. Save the world—or remake it.

As betrayal tears the team apart and sacrifice becomes the only currency left, Elias must confront the ghosts of the past—and decide whether he's humanity's last protector, or its greatest risk.
