The Sky Remembers What the World Has Forgotten.The soul of the world has fled, leaving behind a necropolis of iron and a sky choked by sulfurous smog.Astrid is a scavenger of the First Age, a pilot flying on spite and "borrowed breath" in a graveyard of high-elven craft. She has survived the soot-stained ruins by building iron walls around her heart and tending her own wounds since she was a child. But when she pulls Kael-an exile with a past as jagged as the Elder Spires-from the wreckage of the North Reach, the solitary life she's built begins to fracture.They are hunted by the Architect's hounds: silver-runed drones that never tire and never miss.Together, they possess the Indigo Map, a relic that doesn't just show the way-it breathes, pulses, and wakes as they fly deeper into the forbidden Cloud-Sea. As the firmament begins to tear open with void-fissures, Astrid and Kael must navigate a landscape of storm-leviathans and ancient forges to reach the Star-Root Citadel.In a world where physics is a myth and safety is a trap, two broken souls must become each other's anchor.Astrid must decide if she is willing to stop running and finally face the fire of her own lineage. Because in the heart of the void, the greatest danger isn't the falling sky-it's the terrifying realization that she finally has something worth losing.
