Huehue Tonatiuh, the last great eagle warrior, has died. His tonalli - spirit - finally free from the chains of a crumbling world, is swept into the unfathomable mystery of the thirteen Aztec heavens. Without a body, without weapons, and without certainties, he must face his creator gods, forbidden secrets, and truths that not even the Mexica people ever came to understand. Join the soul of the warrior on a mythical journey where love, betrayal, the fury of the deities, and the greatness of ancient cultures intertwine. Each heaven is a trial, an echo of a world that burns, that sings, that remembers. A novel that not only tells the story of a warrior's passage through the celestial houses but also invites us to rediscover the ancestral view of death, honor, and eternity.
