The world is changing It just happened in one month

(I had one then I tried to put it through and didn't work)

I'm a new author I don't know what genres to put beside the ones that I think is right if you think you have one please let me know and I will see if it fits

This story has been cooking in my head for a year I been slowly working on world-building but then I asked and people said I should just go for it
