The jungle remembers what the world has forgotten.

When Mark Alejandro Lejos enters the legendary Aripo Caves, he brings more than just a tourist's curiosity. He carries a secret, awakened by a pendant that now burns as part of his flesh. The caves are alive with ancient magic, and they have been waiting for him.

Teaming up with the enigmatic Zara Cazabon, Mark is thrust into a battle against forces he can barely comprehend-a vengeful serpent god, the ghosts of failed Guardians, and a dark family legacy. As the line between memory and nightmare blurs, they must decipher the truth of the Winged Jaguar. But in a place where every secret has a price, the ultimate cost may be their very souls.
