But when the tales begin to warp, birthing monsters and rewriting entire histories, even the Library’s endless shelves can’t protect him.To survive, Aether must step into dangerous books where myths breathe, legends bleed, and the wrong choice can erase you from existence. Each journey brings him closer to the truth of his creation—and the author who penned his fate.He is not the hero of these stories.He is the flaw in every one of them.
