Y/N Potter was never meant to come back. Presumed dead for years, her sudden return to Hogwarts shatters everything Harry thought he knew about his past—and himself. But the girl who stands before him is not the sister he imagined. Sorted into Slytherin and shaped by a world he doesn’t understand, Y/N is caught between two identities, two loyalties, and two versions of a life that were never meant to exist at once. As Hogwarts divides around her and the wizarding world edges toward war, Y/N must decide who she is beyond the name everyone claims—and whether belonging anywhere is worth losing herself entirely.
