The problem is that I can't say anything about it just yet. It's a major element of Part II, and it sets up an interesting triangle, but not in the way you might think. If I told you, I'd have to kill you.
Seriously. You don't want that.
The reason why I mention it at all is that it means I have to rework some ideas I have when I get to that point of the book. It weaves in an element of mystery that will provide some tension with a few characters. I'm excited to explore this aspect of the relationship of these three individuals, and I'm also introducing a concept I have never seen before in any fantasy novel based in Greek mythology.
I'll be getting to The Edit soon, but first I have to grab some food and go to my summer job.
