The rough draft is coming along nicely, with the final sequential scene finished. However, it's not done yet, as I still have a gap or two to fill, scenes to rewrite, edit or beef-up and a few minor, minor details to put into place. But the entirety of the book is set: beginning, almost all the middle and the ending. The toughest part is putting on my editor's cap and reading with a jaded eye, cutting out the bits that don't quite work or just go nowhere.
Having a complete rough draft is exciting and the next best thing to actually holding the finished product in my hands. I think creating a book must be akin to filming a movie; write a screenplay, film the scenes, edit the best bits in and throw out the chaff.
At the end of a long road, it's good to see the destination coming up over the next hill.
