Hi! If you want to discuss the book post-bookclub I’m certain that you’ll get responses in the bookclub threads. I know I still watch them actively as do several other of the people who initially read along. The コンビニ人間 threads also have some really good discussion that could be interesting to read as you go.
Also, consider checking out the Sayaka Murata Bookclub! We’re actually starting a new pick in a few weeks if you want to read along!
You’re going to love コンビニ人間. Murata is really a fantastic author.
