I rather think this is it.

I've written five pages of notes,  the basic A to B of a plot, a set of characters (that I still need to add to), a series of ideas I need to get in. I have my main characters already, of course, since this is a sequel to Entanglement. I know what they're doing, I know where they're going. I haven't started writing yet, as such, but soon (she nodded wildly to herself). Soon.

Yes, I rather think this is it. What a relief.
