'River of Bones' has powered past 9000 words and I've had another chance to apply some of my own writing lessons to it. The story is expanding and evolving and I've added in some scenes with the bad guys. Necessarily then, they've needed to become more than knife sponges for the hero. Instead of making them all sympathetic with back stories of their own and mothers who love them, I decided to add conflict amongst them. I changed them into a band of people who are not really working together but rather are cautiously allied for potential mutual gain. There's a big difference in the motivations now. This all goes back to a lesson about interesting writing coming from adding conflict. Typically, we genre writers think of that as more danger for the hero. I thought it might be interesting to add some danger to the villains that wasn't just coming from the edge of the hero's weapons.
But really, this all stems from the fact that I needed scenes to weave between the hero's journey that is the main story. Non-stop narrative from the hero's point of view gets a little boring. Switching around and following different characters makes for much more engaging reading. Thus the birth of the B-story.
