I sat doing a jigsaw puzzle, the winter sun pouring in. I felt guilty about not working on my proposal. I have completed the overview and am now working on the chapter summaries. In truth, I was thinking about them, and the arc of the book's narrative, as I hunted down puzzle pieces. As I've said before, a jigsaw puzzle is an excellent metaphor for figuring out a book. A piece at a time, the picture comes into view.
