This is an AU of Season 3 that I wrote before Season 3 came out. After her death, Marcy finds a notebook in the castle and begins to write down her thoughts, but little does she know, a lot more adventure than just journal entries awaits. Spoilers! I don't own the show, Amphibia, but I do own the story and the art for the cover and at the end of the story. There is also a Gravity Falls crossover chapter in here, so I don't own Gravity Falls either. Please try to avoid swearing or saying inappropriate things in the comments. Thank you.
