Mabel and Dipper return to Gravity Falls three years after their life-altering summer vacation spent with their Grunkle Stan, to find that Gravity Falls never stops being, well, weird. As the twins encounter old friends and reconnect with the supernatural inhabitants of Gravity Falls, new dangers lurk just outside of the knowledge of Uncle Stanfords old journals.

Trapped and too scared to tell anyone, Mabel struggles to hide her abusive relationship.

To defeat Bill, Dipper and Mabel transform into beings far more powerful than the demon. But after the battle is won, and they seem to be back to normal, they both know that they are forever changed. They aren't truly human anymore, this much they know. But what exactly have they become?

The Pines twins have been steeped in mayhem, mysteries, and magic every summer since they were 12 years old. Coming back home to Piedmont, going to high school, acting normal? All those things make them stick out like a sore thumb. When you ask outsiders about the Pines twins, you get a mix of strange stories and casual observations.
