Last night, it occurred to me that an element of one of my subplots was not imaginative enough. I thought about it for a while, and came up with what I think is a much better idea. This is where writing a plot summary comes in handy. It was easy to change a bit of description in the summary, and now that concept is very different. I have started writing that part of the book, and I have to say that I am much more enthusiastic about how it is going than I would have been with the way it was originally.
