My latest novel, Murder For A Grandmother is rolling along since I went back and changed a lot of my original chapters. It was the old kiss principal. I cut out a lot of complicated plot twists and some sub-plots and got back to the main theme, which is Grandma solving the murder and saving her grandson from the hangman. I still have a tendency to try and save some of the original but I find it much easier to delete it and trust my subconscious to remember any particularly good bits that should go back in.
I also googled faces for my characters and pinned them up on my wallboard, which I find helps as I can glance up and say "how do you feel about this" or "what are you going to do next" and their faces often give me the answers.
Since I already have a publisher who has at least expressed interest in the idea for this series I am feeling quite confident about it. Ideas for sequels are bubbling in my brain and it is hard not to stop and write them now. Priority has to be to get one complete draft of the first one which I am happy with. Then maybe I can jot down some notes for others before coming back to the revisions.
