I will be posting (new) Chapter 19 later today. Some errors were pointed out to me, and I have made corrections. Also, while re-reading/Editing Chapter 19, I noticed I was effectively writing some "Flashbacks" I also did this in Chapter 17. I do not like how I did this.
Timeline is an important aspect of this story. While most of the characters are not aware of what others are doing elsewhere, the Readers are.
I had already writen some 20 chapters, before I discovered the issue with Time Zones between the USA and Mexico, regarding Daylight Savings Time. Fortunately, I had not yet posted them. I was able to re-write, or in some cases, merely relocate certain elements of the story.
Chapter 19 has been bedeveling me. I am establishing several crisis in a beliveable manner. I believe I have it prepared for posting. I have relocated several paragraphs to Chapter 17, and a similar bit of chapter 17 to chapter 15. If you have already read through to the end of Chapter 18, I don't think it is neccessary to go back and re-read earlier chapters just for the minor changes I have made.
