In a world where lineage is a literal prison, Elara Vane is a Bone-Binder, cursed with an ancient magic that allows her to mend the broken—at the cost of her own vitality. She seeks a quiet life as a village baker, hiding the glowing marrow that hums beneath her skin. But when a local boy’s life hangs in the balance, Elara reveals her secret, inadvertently forging a forbidden connection with Silas, the town’s steadfast blacksmith.
Silas isn't just a witness to her power; he becomes a part of it. Through a desperate act of "Resonance," the two find their souls and skeletons tethered by a Star-Iron bond. As the ruthless Vane Matriarch and her "Hollowed" assassins hunt them to harvest their unique power, Elara and Silas must journey to the heart of the Ossiary Vault.
