I spent some time today working on my structure. I moved a few scenes, and added some more scenes to my outline. I've only been working on my book for a few weeks, and I'm currently at 15,000 words. Much of my time has been spent outlining the book, and doing research. I have the basic story established, with a narrative flow I'm comfortable with, but there are a lot of holes that need to be filled. I read about writer's discovering unexpected story development, letting the characters take them to places they hadn't considered. I had a good day yesterday in that regard. I was writing about the death of a character that I wasn't sure how to handle. The narrative just seemed to flow, without much pre-conceived idea on my part on how things would play out. I was very pleased with the result. I do tend to think a lot about the scenes and how to write them, but this was just a free flow of writing that turned out better than if I had tried to force it.
Have you had experiences of the story taking on a life of its own? Have your characters taken you to unexpected places?
