Anne's Journal for the Apocalypse

Anne Savage is a 15-year-old living in the end of the world with three friends, her big brother, and all sorts of new monsters. She was separated from her big brother at the age of 5, met back up at age 13 and got split apart again after giant portals opened up in the sky, how will life go on as normal for this young girl? Luckly we will know by this journal that was left by her, let's get into reading!
!!!Warning there are very sensitive topics and most likely a lot of cussing!!!!
I also do not own The Last Kids on Earth or any of the characters other than Anne who is my own OC and I have aged them up from 13 and 14 to 15 and 16
