Sam and Dean find a case in a town they've never visited before: Gravity Falls. After speaking to Dipper and Mable and finding out more about the town, they reveal the strange truths and secrets behind the town. With Dipper, Mable and the rest of the Mystery Shack team, Sam and Dean must face beasts and monsters that they have never even imagined of seeing before. Notes: First off, this is what I like to call a 'follow on' story - this means that I WILL PUBLISH ONE CHAPTER AFTER ANOTHER INSTEAD OF WRITING THE FULL THING FIRST. Second, this is a fanfiction, therefore none of the characters are mine. All character credit goes to the creators of Supernatural and Gravity Falls, Eric Kripke and Alex Hirsch. This is also my first story, so it probably will not be that good of a story. Please take this to account as I do not want any discrimination. I'm not that good of a writer, so I'm sorry about that. I hope you enjoy anyway! ***CONTAINS MILD BLOOD/GORE AND A LITTLE BIT OF STRONG LANGUAGE***
