Prologue

Dipper and Mabel are finally 16. But, ever since their 12th summer in Gravity Falls, they decided to move in with their Grunkle Stan. Of course, they helped him build a house next to the Mystery Shack and still help out, while going to school in the new town, with better jobs and police. One day, Dipper runs into a girl who happened to be picking flowers for her older brother and sister. Her sister was sick and Dipper decided to help the young girl out. Later that same week, Dipper found that a strange thing had been surrounding the town and watching him. With a little help, Dipper will be able to stop it. But when the plan fails, Dipper finds himself asking an old enemy for help. Can Dipper save Gravity Falls before it's too late? Or will he be trapped in a world of darkness, with only his friends and family?
