"A little mischief won't hurt..."
A Black in Gryffindor was never good.
And they're right.
Carina Black's name isn't as famous as the Boy-Who-Lived, she was not praised for saving the Wizarding World from the Dark Lord, she was more known for being a traitor's daughter. But she wouldn't let her father's supposed crime over shadow her.
With her best friends, Roman Alston and Theodore Nott-- both Slytherin. The three (two rather) will bring chaos to Hogwarts. Along the way they would fight a war that could bring out new relationships.
