Blue - Harry Potter AU

[Draco's Sibling AU] Draco's younger sister, Aquila Malfoy, had always been a patient child, and had always done everything her parents asked of her. She was loved, brought up right, and - most of all - happy. At the age of 11, this all changed. She went from the perfect Malfoy child to a misfit. A hero to a traitor. She became a Ravenclaw.
