A Gravity Falls Fanfiction Mabel and Dipper are back for their 2nd summer at the mystery shack. Mabel finds a spell in Dipper's journal, and without thinking reads it. Nothing will ever be the same again... This book will be in the perspective of Mabel, if I don't specify, just to let you know. (p.s. This is NOT Reverse Pines! This is my own creation. I have no sympathy for haters who were to lazy to read the desc.) Enjoy!
