The Potter Twins and the Philosopher's Stone

Harry and Rose Potter have lived with the Dursleys as long as the could remember. Their parents had died in a car crash when they were only a year old, leaving identical lightning bolt shaped scars on their foreheads. One day, two letters arrived in the post with the twin's names on them. Join them as they are thrust into a whole new world filled with friends, foes, magic, and... fame?

I don't own Harry Potter or any of the canon characters, obviously. I do own Rose though, she's mine.
