Every one has secrets right?
You're a new student at falls high, there you meet people such as Mabel pines, Dipper pines, Candy and Grenda and Pacifica Northwest.
Dipper gets bullied by everyone at school, including his own sister (sorry to Mabel fans I love Mabel but this is just for this story I have to do it for my idea to work :/) he feels rejected by everyone, they treat him horribly, if only they knew his secret, maybe then they would fear him instead? What happens when you save dipper from eternal solitude?
Note: in this story dipper and Bipper are the same person, it's just that dipper is his human and his true nature aka his demon form, in which case he becomes Bipper. I hope this makes sense to you, if doesn't I'll explain in the comments
I do not own any of the pictures shown in this book nor do I own any of these characters, the only thing I own is the plots of this story and the readers personality
The Mystery Twins are 19 and off to college. But things are different now. Mabel will be in California, while Dipper studies at the new Gravity Falls Community College. And if that's not enough, Dipper is forced to face Bill Cipher again. The demon is determined to destroy the minds of the Pines family. But things change, for better or worse. (This is more of a rough idea. Once the book is finished, I will most likely change the description)
Disclaimer: I don't own any characters, fanart, or have any affiliation with Gravity Falls. Just a fan writing a fanfic.
