No one is being forgotten.



Here's a bit of summary from the author.



The kids find themselves in the land of the dead, they realise that the book Dipper holds in his hands has something to do with it. The mysterious thing belonged to their grand uncle, and he must know how to get them back home. Asking for help is kinda scary and therefore out of option, but it quickly becomes pretty obvious they won't find Grunkle Stanford by themselves. That's when they stumble upon an alebrije- little dinosaur-like creature, which leads them to their uncle.. Stanley??

That's where things get complicated, as Dipper and Mabel also find out they must get to Ford before dawn, otherwise there will be no going back.
