Amy Harn is the twin sister of Harry Potter. Well, technically she is Amy Potter, but she was adopted, so her surname would be Harn, but she's still a Potter, 100%. She is almost more famous than her brother, Harry. She was the lost twin. The one they think died. But there are still wizards, such as Dumbledore, or even Snape, who think otherwise. Who KNOWS otherwise. And Amy will face challenges that not even Harry could imagine.
