No, please don't. Please don't make this into a serial story. It's perfect just the way it is.

I was resigned to Harbor dying. It was a very good resigned, for the lead up to his imminent death was very, very, very well done. However, when Brody comes up with the gun and threatens to shoot Bethany, the first thought through my head was, "WTF?" I was so incredibly disappointed that the author was going to cop out and introduce a fantasy element just to save Harbor.
But then Simon Jimenez just turns it all around and leaves the fantasy element behind, and instead focuses on the relationship between Brody and Harbor. I absolutely LOVED the little flashbacks of the two. The interactions between Brody and Harbor were so well-crafted...Just unbelievable.
I really hope the author doesn't continue this story. The ending of 'Chapter One', as it's called on his page, is a perfect ending for a short story. Sure, there are questions left unanswered, like that of why Brody was able to see the Bethany, but that doesn't matter. Lots of stories end up with questions left unanswered, and while that usually doesn't work (it almost never does), if it's done well (like this particular case) then it works. It absolutely works.
My favorite part of the entire story:
Simon Jimenez, when it comes to my list of favorite authors, I can be very, very, very picky. I can say with certainty, that based on this one chapter/short story, you are definitely on my list.
