andr0gene, I understand that you try to shift from different points of view throughout the Confounded series. Because of this, I have a few suggestions that you may want to consider. First, I would shift the story's focus to Tom for a period of time. As the reader, we don't know a whole lot about how he views the world: including his insights, frustrations, likes, etc. I believe that Tom's personality could completely open a new door of possibility if you delve into it a little further.
The second thing that I would consider is adding a new main character into the mix. This could lead to a new jealousy or love affair between one of the older characters. Think about it, and best wishes.
