The Thornbound Vow

When Sera Vance inherits her great-aunt's crumbling estate, the hinges scream like something waking, and something has. Beneath layers of dust and silence lies a sealed archive of forbidden maps, a sentient voice named Atlas woven into the walls, and a thornbound vow that has bound her bloodline for generations. The Thorn Wardens are dying. Sir Aldric, thought long vanquished, claws his way back toward the mortal world, and the Unmaker, an entity older than the realm itself, begins to stir behind its prison of thorns. Guided by the spectral memory of Elspeth Vance and haunted by the mysterious Shadow-Child, Sera must decode the cartographies her family died to protect. Bastien Halrec and Caelen Vrye stand at her side, but Arbiter Vaelith watches from the shadows, and not every ally is what they seem. As the Glass-Queen's domain collapses and the Previous Cartographers' warnings become clearer, Sera faces an impossible choice: fulfill the vow and sacrifice her bloodline to seal the Unmaker forever, or shatter the covenant and risk unleashing darkness across every mapped world. The hinges have opened. The vow remembers. And the inheritance she never wanted may be the only thing standing between existence and oblivion.
