The Sister of a Certain Slytherin

What if Draco Malfoy, a famous Slytherin boy and the rival of Harry Potter, had a sister?

The reason Draco never spoke of Madison Malfoy is because Madison is a disgrace to the Malfoys. She's a down-to-earth, sensitive first-year in Gryffindor, who has friends who have befriended Harry Potter - in fact, she fangirls him herself. She has no knowledge about the Dark Arts and hates whoever Draco worships.

But now we turn our eyes away from the boy who is twins with Draco Malfoy. Now we look at Madison's side of the story. Now we look where Malfoy is afraid of looking, now it's Madison's turn to tell the tale of being the sister of a certain Slytherin.
