First 700 words of Book II are down and it feels daunting.
My process involves a lot of layering. First layer is basic actions/thoughts with lots of wholes and gaps. It feels like an overview, rather than a chapter.
Next draft layers in closer perspectives and minor details, has the characters engaging with each other and events.
Next draft slows down the narrative. Adds in those richer details and emotions. Fills in all the gaps. Once in this stage it's ready for editing.
