First chapter of Chamber of Secrets.
Since this is looking to be the solid winner and I want to get started on writing the next chapter of something, I have begun plotting out the summer. No real words for the story yet, but better to have something planned than nothing at all.
Edit: Lucius Section is now written. That was fun to write. I think I'll keep that as the last section. Feels appropriate to end the first chapter on that dark note.
Edit 2: Chapter is WRITTEN! Going through editing. So glad it is written in time for my New Years Resolution.
