Why did I do this? Why is this story any different than any other science fiction? My personal reasons were that, as most authors, I have an agenda. I wanted to express my ideas in a readable format. My characters are presented to look like us but are so different than us. Or are they? I wanted to express a projection of what may happen if we continue our current path of liberty erosions into the future and have reflect it back upon ourselves. Our world today has so many conflicts between, neighboring countries, between religions (though better than it used to be), and between men and women. My story tries to address most of these issues. But in all dilemmas, even if you solve one problem, another rears up to be addressed.
I chose science fiction because I could make up characters and scenarios, not of this earthly world, that seemed more challenging to write about, and thus avoiding hurting a real person's feeling. So I chose Mars. As our science information continues to grow and inform us, it's a good chance that we will eventually be settling on Mars and our Moon in the future, which also explains the 'when.'
Writing this story has broadened my knowledge from our universe to exotic tunnel digging machines. The internet is abound with this type of information to help any writer with certain details that one doesn't encounter in everyday life. I also feel that the mechanics of putting this story together helps me focus in life better.
