» I didn't know you had a sister, Potter. «

Six rulers of Slytherin. One blood witch. A house full of secrets. And no one's getting out clean. Serena Deveraux was never meant to return to Hogwarts. Expelled for blood magic. Vanished for four years. Now she's back at Hogwarts-with war on her heels and two boys who could ruin her. One touches her like she's holy. The other like he wants to watch her burn. And the worst part? She wants both. Theo is the calm. The quiet. The safe. Mattheo is chaos. Fire. Everything she shouldn't want-but craves anyway. Caught between prophecy, blood, and betrayal, Serena must choose who to trust-before she loses herself completely. Because the girl they sent away? She's dead. And what came back wants revenge. Two boys. One war. And a witch made of something far more dangerous than magic.

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.
