Harry Potter's twin sister, Alexa Potter, has grown up to be the one to defend herself and friends and she will stop at nothing to see Voldemort gone for good, for the good of the Wizarding World and the Muggle World.

The night Lord Voldemort killed Lily and James Potter and attempted to kill not only Harry but Hannah, was the beginning of a life full of adventure, loss and love for the Potter twins.

With the looks of both her father and mother plus the lightning bolt shaped scar on the left side of her forehead , Hannah will have to pass through a lot of dangers with her friends and family.

"You're a brother, Harry." Hargrid told me as he gave me a sad look. I was beyond confused. "I'm a-a what?" I stuttered. I shook my head and pushed my eyebrows together. The only thing that was running through my head was 'I might still have family' but I knew that was crazy. The only family I had left was Sirius, that was it. "A twin actually. 'llow me ter explain, when He-Who-Must-Not-Be-Named killed yer parents that night, he knew that the prophecy stated that a boy would be the end of 'im. This was a problem fer ya, but not fer yer sister. Of course, he still tried ter kill ya both, but when yer mother's love protected ya, he thought it was yer sister. Voldemort knew he didn't have much longer, so he decided in order to 'urt ya more, to take yer sister from ya and place her in a wizard home. For some reason, Voldemort had a soft spot for yer sister. No one, not even Dumbledore is quite sure why." He paused and let me wrap my head around it. "What happened next?" I asked, frantically. Was I dreaming? This couldn't be real. "She grew up! In a safe 'ousehold with good people. She knows she was 'adopted' but nothin' else. The reason I'm allowed ter tell ya this is because, she's coming to Hogwarts this year, with the Beauxbatons Academy of Magic for the Triwizard Tournament." I couldn't move. I couldn't think. "I know ya'll be wantin' ter meet 'er, but ya can't just tell 'er she's yer sister!" I nodded slowly, still processing. "Get ter know 'er first, become close friends. Then, we'll intervene and she'll learn what ya just did. Now run along, and only tell Ron and Hermione, and anyone else you trust!" Hagrid said and I opened the door. "Oh and Harry!" Hagrid grabbed me. "Her name is Hailey." /// Harry's fourth year starts off quite different from his previous ones, by finding out he has a twin sister. *BASED on Harry Potter and The Goblet Of Fire* *May be considered mature by some audiences for language and intended mature subjects*
