The Virus (Prologue)

I basically decided to to a gravity falls fanfic that will tug on your heartstrings and make you bawl your eyes out. Hehe...I'm so sorry.
Anyway, the twins learn of a zombie virus that is spreading rapidly through the U.S., and must team up with people like Ford and Bill to survive the zombie apocalypse. They must fight their way through, survive and try to find a cure for the virus. I do not own Gravity Falls or the characters, but Ido own the storyline
