First off, I'll submit chapter 22 later today. I can't tell you exactly how late that will be. It got one review so far and I'm waiting for a second but will submit it before midnight with or without it (my time that is, GMT + 1:00).
I am annoyed as much as you are that my writing and release schedule still isn't back where I want it to be, but I can't help it. The reasons are out of my sphere of influence.
This leads to another notion. I am posting this story chapter by chapter but it isn't a serial. I do it like that because it's more fun for me but it also has a disadvantage. Released chapter by chapter you readers might feel disappointed if nothing extraordinary happens after you had to wait weeks for a new update. Sometimes I have to remind myself I'm writing a novel and not a series. A novel needs pacing, otherwise the story will read like the evening news when it's completed.
So I beg for your patience, it's always calm before the storm.
