The Dark Lords' Pawn

Miranda was Tom Riddle's beloved twin...before Gellert Grindelwald obliviated him. She was then raised by Grindelwald, but guarded from the outside world, ignorant of the growing darkness. In 1944, however, she was spelled asleep and hidden for her own protection. Wakened in 1997, Miranda sets out to find her brother, but finds a certain Chosen One first. Harry/OC Rewrite
