Good news everybody :-) I have finished the chapter plan for the novel I plan to write. I'm quite happy with it overall and it presents a good flow of events to bring the story to its conclusion. I can't start writing properly for a few more days, so I'll take the time to keep reviewing and tightening the plan.
I am starting to worry that 50,000 words is a lot to write in a month. But I do have the story mapped out and hopefully once I get going it won't be as daunting.
