Well, lately I've been sort of putting aside Nanowrimo planning for a bit. You know, there is such a thing as too much planning. So I just went through the manuscript of a novel I wrote during high school. I think the characters are good and the premise is all right, but there are a lot of things wrong with it. So I've somewhat outlined a plan of attack for overhauling it sometime in the near future.
As for planning for the background of this year's Nano? Today I borrowed some books from the library about Cyprus antiquities, mysticism in Christianity, and foxes. Yep, totally disparate subjects, but somehow I'll link them altogether.
