At last! I've recommenced editing Termion. Just added a Tarc section in chapter 18. Still got part of the chapter to go through, but I'm making progress. Yay!
ETA: near the end of the chapter, had something funny happen. I'd deleted some material because I changed the viewpoint. I wrote a sentence. Get to the next paragraph, which I hadn't read today, and the exact same sentence was there! Clearly my muse knows exactly what she wants to be said in this scene, even when I come back after a long break!
