I've started to work on chapter 12, so you can see the general idea. However, as there will be 4-7 people on the trip, my usual structure based on the passages seem to be less useful as general. I have a couple of ideas on how to manage the content, but I will decide during the writing.
I wanted at least one chapter that would be a little lighter and looser than usual. Many of situations I will present happened in the real-life, so I think I will dedicate this chapter to all girls I knew that didn't give up the trips and faced them during their periods. I hope that I will be able to show that absurd atmosphere. ;)
Chapters 13-15 will be quite crucial for the story, as they will focus on Caroline's attempts to defeat the Parity and change back. As I imagined some scenes nearly 2 years ago, I'm really excited to implement them into the story. :)
