Dipper and Mabel are both juniors at Gravity Falls high school. On the first day Dipper gets a new history teacher. This is BillDip.

(This book is VERY old and is currently being rewritten) Dipper Pines is a young adult male who has recently gone back to Gravity Falls during his gap year to spend some time with his Grunkles before deciding on what to do with his life. But after summoning on old dream demon enemy in his first week back, he had a lot more on his plate than just his career. Is the new demon he sees really what he seems?

The one who causes death, Bill Cipher. The ones who bring life, Dipper. And one who keeps the peace between the two, Mabel. Life and death, exact opposites each one barely able to dominate the other. Some say their enemy's fighting for power, others say there friends staying out of each other's way. But just a few know the truth about Life and Death and it maybe time for others to learn as well about the relation Dipper Pines and Bill Cipher shared...

[Adopted by @Ghosty-and-Cloud, @dreamdemonlord, and @kelala_wizner] Weirdmageddon is ending and everyone in Gravity Falls is there to witness. All the Interdimensional criminals and nightmares that Bill called his friends are being sucked back inside the rip. But Dipper's decision changes Bill's fate. "PineTree... Let me do this... Please." Dipper remained silent for a moment. "Alright Bill." [Billdip] I do not own Gravity Fall people! But I'm a major Fan ^^
