Dipper, Mabel and Stan was in Gravity Falls. When Dipper Found one journal, two journals then three journals. He didn't know who was writing in it so Dipper hid the journals from Mabel and Stan. At night he would read what's in it. In the journals was stuff that he didn't know about Gravity Falls. Mabel is like a normal girl but when something bad happens she  will tell Dipper to do something. Dipper will look in the journals and he will see in the book how to make it go away.
