When Diego del Sol, a teenager with amber eyes and a tender soul, embarks on a school trip to Teotihuacán, he never imagines that his roots—and the fate of the world—are about to intertwine. What begins as a simple excursion soon turns into a mystical odyssey after a fall connects him to ancient prophecies and mysterious beings. Marked by the loss of his grandmother, the matriarch of his family, Diego must confront his past, redefine his lineage, and uncover the power that runs in his blood. In a modern Mexico pulsing with the echoes of its Mesoamerican heritage, myth, mystery, and personal grief merge into a moving tale of transformation and legacy.
