I discovered yesterday that a character that I totally forgot about could be combined with one that I inserted sort of randomly, which will be interesting to fix throughout the rest of the book, but I think will make it work better. I'm also finding that a lot of plot is concentrated in a few chapters, while others, though not boring, are not such tipping points. I'll have to wait until I've actually made the corrections, but some of the plot-heavy chapters may have to be expanded...
I think once these edits are made the novel will be in much better shape. It will still need another round like this, but it's coming along. It's pretty fun, once I get up the energy to start. I actually don't know how many chapters there are in the book because I lost count during NaNo and stopped numbering, but I did roughly one per day so that means I'm about a third of the way through right now.
