Well written and thanks for posting.
I will admit that I had a small issue with it. Part of good fiction is the suspension of disbelief. Banning coffee is a good premise but in Spain? Seemed a little odd. Banned by a mayor? Mayor don't really have that kind of power. Profiting off of the misery of others is totally believable but in secret? My mind is wondering how someone could hire enough labor to work the fields without the town knowing what is going on.
I'm not trying to be mean and I'm sorry it if comes across that way. However, I think I would have enjoyed the story more if my mind would let me believe a mayor had that kind of power and that such a large operation could be kept secret.
Otherwise, great story and writing.
Look forward to seeing more in the future :)
