Looking for a specific fanfic where the triwizard tornument becomes an exchange program

What i remember of what ive read of this fic is that harry learns about black families traditions through a book she finds in grimold, she begins to bind her hair and weave magic into it, she starts to take school seriously and gets better grades then hermiony and when the tournament is cancelled gets selected for the exchange program. At one point they go to a kilt shop.
