Life After Death

Based on my current story, in a city wiped out by a necromancer (she started the zombie plague, but the zombies died within hours of being created and contained it to one city). A little girl managed to hide from the zombies, and now survives by taking whatever she needs from abandoned stores (the attack took place during the daytime when the stores were open, so most of them were unlocked). I should write it down, but probably won't because it's already too long and too unbelieveable.
