Clara Thorne, a rational, meticulous art historian, suddenly finds herself the heir to Blackwood Manor. Abandoned and vast, the house is a historical puzzle, but Clara soon realizes it's far more dangerous. The manor is a physical repository of emotional history, where moments of intense feeling—betrayal, fear, and agonizing regret—have been absorbed by the furniture, the wallpaper, and even the air.
Guided by the cryptic ledger of her "eccentric" Great Aunt Beatrice, Clara learns she must act as the Curator of Lost Years, deciphering the house's terrifying kinetic archive. Her mission focuses on December 1952, the Year of Weight for a missing silver locket, the physical catalyst for the manor's enduring tragedy. To finally bring peace to the house and set the violent past to rest, Clara must locate this dangerous relic, venturing into a sealed attic room where a preserved wedding dress holds the final, most devastating echo of a generational betrayal.
