It All Comes Crashing Down

Not sure what this is just some English homework that I made into a short story. Not very good but for my friends I'll put it up here. I don't own any rights to the cover so please don't sue me if it's your work. I can't draw so I used this, hope that's alright.

It's a post apocalyptic, dystopian book and who knows what I will be adding? Polly, Eve and Daniel are the main characters who are all around 14 years old
