They called him a monster.
And maybe he was. When Briar Williams is taken prisoner by a dark wizard camp deep within the Forbidden Forest, she expects to die at the hands of the one who leads it. But it turns out to be Sebastian Sallow, the boy she once betrayed years ago. Instead, she finds herself caged, watched, and curiously spared. Sebastian is no longer the reckless Slytherin she remembers; he's cruel, calculating, and... oddly collapses at random? But beneath his coldness flickers the same sharp intellect and haunted soul that once fascinated her. As Briar unravels the secrets of how Sebastian never made it to Azkaban, his seemingly random failing health, and the camp's twisted purpose, she begins to question everything she knows about monsters-and the man she's come to fear and pity. Meanwhile, Ominis Gaunt-the Officer of Hogsmeade and Briar's long-time lover who desperately wants to marry her-has been convinced by Poppy to save her. Warning: This is a dark, mature, and mysterious Hogwarts Legacy romance. This story explores trauma, morality, and will feature some explicit scenes of violence.
