I've never heard of Voodoo Moon, but I'm glad you enjoyed the chapter Nephylim.
As I've commented in a review response, Chapter 8 has been one of the hardest and most draining chapters I've written, emotionally, second only to the horrific nature of the rape scene. For all that my readers agree that it's a powerful piece of writing, I loath that scene simply because it was too draining on me. I wrote it in one, gut-wrenching, soul shattering go. Don't ask me the details, I've deliberately forgotten most of them. I can tell you what I did; I defined the physical aspects of it, and then placed myself in Jason's head. I had to let myself be raped to write that scene (not literally, thank whatever gods you worship!) and the horror of having to go back over it and edit it down still haunts me. I basically had to get someone to hold my hand and help me prune it down to get it to an appropriate physical level (without, 'thankfully', detracting from the emotional horror of it).
Of course, other chapters have been harder to write not in the emotional sense, but just because I didn't know where to go, or (more frequently) how to go there. I have a Plan for this story, and I know who is going to die. I know who is going to live. And by the Light that hurts sometimes. (Note: "Light" is a deliberate story plug that won't make sense for a long, long time...)
