I'm making what looks like the final edit. The publishers have the draft copy so they can see what the content is like and can plan their marketing strategy and get a feel for the book. At the moment, I'm sitting on nearly 60 000 words.
Having not looked at the book for two days to get a fresh approach was a great thing to do and feedback from one of the testers pointed out an inconsistency in the format which I know would have bugged me if it went to print without being addressed. The short break has let me focus on what I've said already and what I have meant to add and hadn't (thinking I'd put it in somewhere else) without repeating myself in an annoying manner.
Feeling pretty good about this.
