Hello, there is a large number of ongoing book clubs in the community, nicely organized here
In particularly 1Q84 is being read right now:
Some clubs have weekly read-aloud sessions on discord, while forum threads have shared vocab spreadsheets and discussion of grammar etc.
Level-type clubs (absolute beginner, beginner, intermediate, etc) nominate and vote on the next book choice. But anyone can create “stand-alone” club with the book they like.
