As I do with all of my series I get to a point where, because of the gap between writing each chapter I need to completely reread the story from the beginning. (Perhaps this is due to my age). So, prior to writing chapter 7, I began reading and of course made changes which improved and tightened up the structure of each chapter which led to a better Chapter 7. So I have reposted all of my chapters which makes it possible for my new readers to a better grasp of the story. I wonder if all writers do this.
