The French Potter

You all know the story of the boy-who-lived, well, little did anyone know that he wasn't the only Potter child. He has a twin sister named Hope. The reason Harry don't know about her is because when Dumbledore sent Hagrid to go get Harry, he also had Hagrid drop Hope off in France, at no other then the Delacour's. When people find out who she is, it earns her the name The French Potter.
