I'm in the process of working on the rewrite of Book Two, and I'm at least 29 Chapters into it, which is over halfway. The good news is that I've figured out how to address an issue that I've been wrestling with.
I won't really call it a block. It's one of those things that I've been asking myself how far down this rabbit trail do I go, and is this something I should do? I was trying to figure out the best way to look at the plot. Situations like this one are where I'm faced with those thoughts I had put on the back burner to deal with later. Then it's time to, as my mother would say, fish or cut bait. You have to decide which one you want to do. Nobody can help me with those decisions. They don't know enough about where I'm coming from or where I'm going to help.
