Chapter 1- Marco's Moment

In the summer of 2013 (Dipper, Mabel and Rory are going on to grade 9, while Star and Marco are going on to grade 10, assuming that their shows take place around the same time), Dipper and Mabel were coming back to visit Gravity Falls for the summer, while the Diaz family decided to move to the sleepy town of Gravity Falls, just in time for Star's 100th day on earth party! In Gravity Falls, anything could ruin the party. Gnomes, Weareolves, a selfish blonde haired girl with a love for gore... Anything you can think of! (Some Starco, and some OC x Dipper (not much)))
