I think I'm going to post chapter 20 a little bit early - possibly on Friday. I want to give everyone a chance to catch up with chapter 19 if they haven't already but I'm eager to get part 1 finished before Christmas so that I can take some time off and get ready for part 2 in the new year.
and there's a lot of prep, lots of building and loads of characters to make. Also I'm doing an exam scene so I need like 25 students all posing at desks, which is bringing me slight dread.
Anyway, watch this space, chapter 20 coming in a couple of days!
