I don't own gravity falls or steven universe. There will be no ships (maybe ConniexSteven? It's barely mentioned), this is not a reader insert.

I updated and added more! There is no second book! Sorry for all those who were waiting! I feel as though this was slightly rushed, and I hope to make better crossovers in the future.

Infinity Train GF: Star's Vanish (Gravity Falls Infinity Train Crossover)

10 parts Complete

In their first summer in Gravity Falls, Mabel Pines had her moments, but to be honest she's been a bit self-centered. Her twin brother, Dipper, has done so much for her and she's hardly returned the favor. Even after going to Gravity Falls, Mabel hasn't learned her lesson and has become more selfish then ever. She demands many things from her brother, and not once has she helped him or said thank you. The twins are now 13 and are heading back to Gravity Falls for the summer. But when Mabel steps onto a mysterious train, she learns about who she is and how she should change. Join Mabel on the Infinity Train as she embarks on the journey of a life time! I'm not trying to be mean, I am not a Mabel hater (well, sometimes) This is just a story for Mabel's redemption. It doesn't even have to be the Mabel from the show, it can be a Mabel from an AU. If you're not ok with that, don't read. I would advise to watch, at least, the first two books of Infinity Train to understand most of what's going on [INFINITY TRAIN BOOK 1 SPOILERS] (I don't own Gravity Falls OR Infinity Train, and, bla, bla, bla, you know the drill. Now onto the story!)
