Stanley Chapman lives off the grid, a soldier with blood on his hands and nothing left to lose. Then he meets Carmen, a woman bound to Ix Zen, an Aztec cult that worships fire as truth. When she disappears, Chapman follows her trail from Mexico to Spain, chasing obsidian relics engraved with a spiral that marks every sacrifice.
Each step pulls him deeper into a maze of cartels, scholars, and believers who kill to protect the secret. The closer he gets, the more the spiral burns into his mind, twisting memory into myth.
To find Carmen, Chapman must face the cult, the past, and himself. Because once you follow the spiral, there is no way back.
