This is a Gravity Falls spin-off that I wrote. It stars Arty, an adventurous thirteen-year old boy and Annabelle, his sometimes moody fourteen-year-old sister. They take a trip to Gravity Falls for a week, and the trip turns out to be Arty's dream and Annabelle's nightmare. There are a bunch of references to the original show, and maybe even some characters may come back (SPOILERS). This is just the first edition of my continous series: "Arty and Anna in Gravity Falls"!
