The House Eaters is nearing the end of part 1 (I envision three parts, each culminating with a supernatural event). One thing I enjoy about drafting a longer work is that characterization can take time, it can be more subtle. I also enjoy how those characters take on their own lives and start acting on their own.
I had no idea that the protagonist's sister exhibited psi until it happened, opening a whole series of plot events and back story. She has a psychic connection to her brother, an echo of something that took place years before the current tale, and it will factor in the climax of the novel. That was a nice discovery.
The book is just under 16K now, so the final draft will probably hover between 40-50 (a decent amount for typical YA). So far, so good.
Last night, I had a POV quandary that nearly shut me down. I've been writing the story in first person. (Surveying the books my students are reading, I'd say POV is about 50/50 in the YA area--I haven't done any real research.)
My quandary wasn't a real problem, per se, just a fear that first person wasn't right (i.e., it wouldn't sell). When I write short fiction, I stick to third person pretty religiously (80/20). I think third person works best with horror fiction, especially short fiction. This book isn't a strict horror tale, but more dark YA fantasy.
