I haven't done this in many years, due to the publishing business. It's exciting to be preparing and researching. I have a cover. I have my soundtrack. I have plot points, a scene list of scenes to write, and character bios all ready. I have a few images of the demonic protagonist I found online. I won't share those here because I don't have the rights to publish them, even electronically. He's an African demon who has a few similarities to Thor. I have the basic timeline worked out as well.
Some elements of research have been into what exactly sends social workers into action against parents, rituals of scarification--both historically and in today's culture, and the exorcism rites in Judaism, Islamic, and Native American cultures. There's a lot of symbolism to incorporate which is something I like.
If you guessed this is a horror novel, you are correct. It's an idea I had a good five years back but never went beyond the brainstorming phase. I plan to report on progress as I go here and on my Facebook page. Whether or not I post excerpts regularly will depend on the other things going on daily. I must, first and foremost, fulfill my caregiver role. Otherwise the move and sale of the business would've been for naught. I'm not 100% confident I can get 50,000 words written, even with taking the laptop with me to hospital and doctors visits. I'm sure as hell going to try.
