I've just finished writing chapter 15, starting chapter 16 strong already. Over the next few days I'll be writing 16 and editing 15.
The thing with chapter 15 is I started it with one title and a ending in mind, but the characters had another plan and now has another title and a way different ending, which makes chapters 16 and 17 easy for me to write. Some times you have to love it when a plan doesn't come together and makes a new one for you.
