Dawn of the Dead x fem!child!reader

You're a 13 girl who just watched your huge conspiracy theorist parents get killed by zombies, thank god your parents are called "nutjobs" or else you wouldn't have your apocalypse kit.

Each chapter goes by about 10-20 minutes of the 2004 movie that I watch while writing to make this as accurate as possible to you being in the movie.
-
Y/N is based at 13 years old because she is childish but not on the level of a smaller child.
-
I do not own Dawn of the Dead or any other characters other than Y/N and a few very minor characters!
