THEY FOUND THE TRIANGLE.IT WAS ONLY THE BEGINNING.The code 9:9:4 has led Melina Orestis and Nathaniel Morton to an uncharted island in the Black Sea—a place erased from every map and guarded by rival factions prepared to kill for what lies beneath it.Buried under the ruins of the Temple of the Two Serpents is the Second Node: an ancient mechanism linked to a vanished expedition, an empty reliquary, and a secret someone has protected since 1991.But the deeper Melina and Nathaniel descend, the more the mystery turns against them.Every clue exposes another betrayal.Every answer fractures a family.And someone they trust is already bargaining with the enemy.They believed the Grail was an artifact.They were wrong.It is a condition—one that cannot be stolen, inherited, or activated by force.
