In a hellish future scarred by endless wars, Earth has become uninhabitable, driving humanity to live on a strange platform in the sky named CIEL. Here, humans evolve into genderless, hairless beings who inscribe stories on their skin. Below, a cult leader enslaves what remains of humanity. Among the chaos, a reimagined Joan of Arc emerges as a warrior with a mystical connection to the planet. Her tale of rebellion, sacrifice, and prophecy will rewrite the fate of all existence. 'The Book of Joan' blends dystopia, speculative fiction, and deep philosophical questions, crafting a narrative that's as unsettling as it is compelling.
