Gravity Falls: Dipper's and Mabel's Guide to Mystery and Nonstop Fun! by Rob Renzetti

Did not finish book. Stopped at 43%.
I was just bored. I think the only interesting part for some adult readers would be the codes, which I don't have a ton of interest in right now.

Maybe a good read for healing your inner child. Might scare kids (and some adults) if they're sensitive to the paranormal, since it's treated as real.
