Tonight, I completed the revisions to another chapter. I ended up modifying several scenes in this chapter, and was even forced to revise other chapters as a result, but it was manageable, and good for the story. Revising material, any material, that spans across chapters is certainly the most difficult thing to do. But fortunately, I have a good outline to help me find related scenes, and when the outline is unhelpful, I can use the Word search function. Three chapters left to go now.
