The Absolute Beginner Book Club will probably have a vote in the next month or so. (I’m not certain of the exact timing for votes.)
The Beginner Book Club recently voted, and will be starting a new manga in early November. (We’re only a few weeks into 耳をすませば currently.)
I know you mentioned wanting to follow along, but just to note you can also utilize older book club threads for discussion and ask questions you may have, even if the thread is over a year old. Many of us get notifications of activity on the old book club threads!
