The marauders and lily travel forwards in time to harry Potters generation, to start their forth year.

What if Lily and James never died on Halloween? What if Harry's parents lived long enough to reach his second Birthday? What if Harry never lived at Number 4 Privet Drive with his Aunt, Uncle and Cousin? What if Sirius never went to Askaban for a crime he did not commit? What if Peter hadn't been made secret keeper, meaning he couldn't tell the Potters location? What if Harry grew up knowing all about magic and Hogwarts and the world he is a part of? What if everything we think is true in the magical world is not? What if the story we know and love is different to how we thought was? Lily and James Potter died before Harry could get to know them, a tragic story. But, if Harry had grown up with his parents what would be different about his life? Who knows? What If things had gone differently? What If?
