Imagine Harry Potter had a younger sister that he never knew about. The characters are not mine and I don't follow the story exactly. This is, I guess you could call it, a re-imagining. Cover by kenval214

No one knows who she is. Except him. And he wishes he didn't. When a mysterious transfer student named Sylvaine Nox arrives at Hogwarts for her seventh year, the entire school is thrown into quiet chaos. Cold, calculating, and powerful beyond reason, she's unlike any witch they've seen before. But Draco Malfoy knows exactly who she is. She's the Dark Lord's daughter. A secret so dangerous it was buried even from his most loyal followers, except Draco. He saw her once as a child. And now, here she is, walking the halls of a post-war Hogwarts like a shadow reborn. Sylvaine is not here to make friends. She's not here for redemption. She's here to watch, to judge, and to ensure her father's legacy is never forgotten. And Draco? He wants to hate her. He should hate her. But hate has always been a breath away from obsession.
