the true story of Marissa Potter

I'm Marissa Potter, Harry's twin sister. When Vol- He-Who-Must-Not-Be-Named attacked our house when we were one year old we both were saved- and scarred. We both have green eyes, dark hair, same skin tone, same height, and the same scar. Basically if I wasn't a girl we'd be completely identical. What will we encounter at Hogwarts school of witchcraft and wizardry? Only time will tell. Disclaimer most character and the plot line and the setting and basicly everything belongs to J.K. Rowling.
