She was never meant to be a hero. But the Chamber has been opened, and the blood is on her hands. Slytherin's most disciplined and undeniably dangerous student, Felicia Forester, is back for her second year after surviving a face-off with the Dark Lord himself. Known for her mastery of precision and her deadly skill as a duelist, Felicia operates by the cunning, self-preserving rules of her house. But as the whispers of the Heir of Slytherin turn into a bloody reality, threatening the innocent students she quietly guards, those rules begin to fracture. This morally gray witch finds herself perilously close to the center of the terror, even as the mounting darkness pushes her lifelong rival, Draco Malfoy, further down a path of pureblood prejudice and hatred. Felicia is forced to make a dangerous choice: retreat and uphold the cowardly reputation of her house, or step into the war for Hogwarts. Her only true escape from the tension is the undeniable, chaotic charm of Fred Weasley, the Gryffindor determined to uncover the genuine laugh hidden beneath the highly guarded Slytherin exterior. When lives are threatened, will this fierce, calculating Slytherin defy every expectation-and her entire house-to fight a secret war for the school that would sooner condemn her than see her as a hero? A Hogwarts AU/Rivalry-to-Romance featuring a heroine who proves loyalty is Slytherin's most formidable secret weapon.
