Book Thoughts

So I've been doing a lot of thinking about this book I want to write. I have a general thought about it as well as the Main Character (MC) and two supporting characters, with a couple of other minor characters. Many of you know my story, "Genoa," and some of you have read a longer version of it, "Genoa (revised)." I want to expand it even more, and for a long time I didn't know where to take it. After everything that has happened to me with JM, I've thought that I would address the issue of domestic violence in this book. I'm thinking also that it would be somewhat therapeutic.
Now I've just got to figure out how I'm going to work on it while I'm going to school. :P
