Alright! My first story with an actually planned plot! Hello again! Yes I'm writing ANOTHER Gravity Falls book... I'm obsessed with this show (Anyway- time for the real description) What would you do if you and your parallel universe self switched places? That's what happened to Mabel Pines and Mabel Gleefull- they somehow switched places. But they don't know how to escape this terrible nightmare they're both sharing. (I swear the book is better then the summary)
