Broken promises (Harry Potter fanfic)

Rebellious and punk wannabe Morganna 'Meghan' Weasley is entering her fifth year at Hogwarts, along with her best friends Hermione and Harry, and her twin, Ron.
But Meghan's world of hair dye and rock bands is crumbling.
Everything is going wrong, from OWLS, to her constant battles with her mother and Professor Umbridge, to always being upstaged by her siblings, especially by her younger sister, Ginny, to the return of You-Know-Who (not that she ever called him that anyway), to those strange reoccurring dreams, to the thing that is bothering Meghan most, her changing feelings for her best friend, Harry.
