The Brave Ravenclaw

When Lira Munns goes to work with her incredibly boring Uncle Robert, she expects her day to be as boring as watching paint dry. No, worse. Watching GREY paint dry. However Lira is not one to do as she's told, and wanders off. When an accident in the Department of Mysteries sends her back in time, she arrives in a familiar living room in October, 1981...AU, not canon. Sequel to BbB
