Once I have my characters developed and my book plotted out all the way to the end, I go to the beginning again: Chapter 1, Scene 1. Now, I write action and dialogue.
I go into writing a book already knowing my characters, much like my artist friend has gone into painting this painting know what her subject is. So, I’ve already done my character research, I already know everything about them, and I already have my faith, romance, and, if necessary, suspense arcs of the project. See my post on Brainstorming Character Conflicts.
Once that is finished, it’s time do the plotting of the story. Basically, I think, “What happens in chapter 1?” Then I give a paragraph or two or three of the events that are going to unfold in chapter 1.
