Even though at times it felt like I would never finish this chapter, I have finally reached the end of Chapter 21. It needs plenty of work, especially the end, but I'll get that when I edit.
Chapter 21 is 3,967 words in length. The novel is now 63,359 words in length, 16,641 words until my goal of 80,000 words.
I'm going to take a few days before I dive into Chapter 22. That one shouldn't take me too long to write, since it just covers the aftermath of Chapter 21.
