Are you Sirius?
Ariadne Riddle and Sirius Black have been inseparable since birth, literally, they are best friends, the only problem is, They're engaged. Now, that wouldn't be so bad, if it weren't for the fact that you go to Hogwarts, and you're fiance is a 15 year old player. No, Ariadne is in for a ride, can she pull through?
Oh, and I forgot to mention, she has powers which can surpass even her father.
Sorry, sucky description, i might have to write another.
