This is an automatically translated description

If you're a fan of the show or just like to be baffled, amused and scared (in that order), then you're in luck! You are holding in your hands the author's cherished diary, in colour, on 288 pages, full of secrets, monsters and mysteries that have never been mentioned before. And it all takes place in the sleepy town of Gravity Falls. You will also learn about the tragic story of Ford, the whereabouts of Blandin, as well as what Dimension 52 is and how you can lure a "gastric duck".

This book is being hunted by the forces of darkness, so keep an eye out for someone who wants to steal it (especially if they have glowing yellow eyes)!

But most importantly, have fun! After all, there is no city called Gravity Falls.
