I don't do this often so bare with me:
When I read a story there's a couple of things I look for, the plot obviously, the language and it's use,
The plot is set in a post apocalyptic future, where humans are struggling to survive, and you've created the plot in such style that you can develop it to have a bit of everything, which is a good thing, you have room to develop the plot.
The language is used very proficiently,correct grammar and spellings. It's narrated in the third person, which gives the reader a feeling of being part of it but not really taking part in the story.
The only comment that I can make is that, I would probably loosen up the language a bit, not in the narration but in the conversation among the characters, keeping it realistic makes it more realistic to the reader, overall very good story and looking forward to the next chapter (7/10)
