Dipper and Mabel had to leave Gravity Falls after that summer. After 3 years they finally come back, will everything be the same? They think that this time things will be different. They had figured iTunes many mysteries the last time they were there so this time there won't be as much surprise, right? Right, until Bill returns to seek revenge. Will the twins and their new mysterious friend have to rewrite the past to save the future of Gravity Falls and themselves? I don't not own Gravity falls or any of its characters but I do own Scarlett. I have added her in so I might repeat a few episodes with her in them. They will only be memories so I won't repeat everything because most of you are up to date with the show and would know what I'm talking about and that would make the book boring. But I'm rambling, lets get on with the story!
