What if I told you that there wasn't just one Potter, but two? Maddie and Harry Potter had only each other left after the parents were killed in a supposed car crash, but when they are separated for their own safety and thrown into the magical world they don't know what to do with themselves. In the third year, Maddie is transferred to Hogwarts to keep her and Harry safe from the mass murderer, Serious Black, and under the watchful eye of the headmaster, Dumbledore.
