The rough outline is that an 18-year old and 12-year old were orphaned, allowed to live their lives similar to Lilo and Stitch's Lilo and Nani. A few years later, one of the younger-child's classmates affixes a cursed envelope to the door, and the older sister opens it. (Ages can be adjusted for realism.) The older sister gets sucked into the last media she touched, which happened to be a DVD she borrowed from the library again since her sister loved it so much. I'm thinking about making them black, since I'm already in the mindset of making the self-insert being a total not-me. I am a racist, but would it be insensitive of me to make the hero distinctly not-white? Would it be a problem if I have her parents acting white and she doesn't encounter personality-shaping conflicts with whites? Would black people like the Avatar cartoon? Do they have bullying problems? Do they have problems with pagan classmates? I would try to find a suitable beta for this before publishing, but I'm wondering if I should bother with the idea of making her not my race.
