I just read the first chapter because I wanted to try an experiment.
- Read the whole chapter without looking anything up. (I ended up looking up a few words I got really curious about, but otherwise I did this.)
- Read the whole chapter again, looking up everything that I don’t know and adding all of those words to the book club’s vocab sheet.
- Add all those words to an SRS program (Kitsun) and study them over the next two weeks.
- Read the chapter yet again with everyone else and see how much more I understand.
Also just some observations from reading the chapter:
The first few pages are a bit tough vocab-wise because it involves some world building. Hopefully the vocab sheet will help less experienced members, and if necessary we can work together to write up a full translation of those first few pages for those that need it. And remember, the first few pages are always the hardest. 
Second, there are some words that have made up furigana for the world/series. I’ve heard that this is done sometimes in manga, but it was interesting to see. I’m going to add guidelines for how to handle these in the vocab sheet.
And finally, based on the first chapter, I think the book will be as beautiful and interesting as we all hoped.
