Back in Time

Hollie had lived a lie. She grew up as Hollie Evans, even though her real last name was Potter. In her 4th year at Luxingburg School of Magic, she was chosen by mistake to compete for the Tournament. In the 3rd task she was kidnapped, and wasn't heard from again until Harry found her. In a duel, something got all over her, and it sent her back to 1979. ( summary sucks i know)
