Oh, how I have been stalling! I'm still procrastinating writing the end of the book and getting on with the editing. I've read articles about editing, I posted an excerpt on Facebook, I read Lisa's book and offered suggestions, but not finished mine!
I guess one good thing I did was rewrite the most recent scene. I didn't know how I was going to end the book when I wrote it, and once I figured out the end I knew I needed that last scene to unfold to a different conclusion so the characters would have the right motivation to take us to the end.
I should have probably saved it for the editing phase, but it was a big roadblock in my head. I can't just leave huge things unresolved and go past them. For my personal writing style I need the story to make sense as I go. So I rewrote much of that last scene and now I'm ready to move on to the climax. Hopefully I can do it justice.
