Slytherin's Girl

The last heiress of the Slytherin name entered Hogwarts, the same year as the-boy-who-lived.
She is haunted by her past, but instead of facing her own ghosts, she tries to fight others'. It's all very sweet untill her jealousy and pride lands her in the middle of the very war that left her an orphan. She will need to face her past and detroy her own blood, or be haunted by the ghosts of those she failed.
