Professor Snape's Apprentice Is a Successor to the Dark Lord

Original Female Lead x Snape. She starts school a year before Harry.

In 1990, bearing a surname from a branch of Voldemort’s family and a natural talent for Dark Magic, she was sorted into Slytherin by the Sorting Hat.

Professor Snape, thirty years old, is wary of her. He knows that, exactly ten years after the Dark Lord’s downfall, even the slightest trace of a connection to him could pose a fatal threat.

“Professor, I just want to survive.”

“Then prove to me that you’re nothing like that lunatic.”
