Thanks to @seanblue for nominating it! 
At the same time, we are looking for a volunteer to run this club. Who would be interested to do this? Don’t worry even if you’ve never run a book club before, there are lots of experienced people around for support if you need it, and there are the excellent Tips for Running a WaniKani Book Club with guidelines and templates and such. If you are interested, please say so in this thread.

Thanks to everybody who voted, and have fun with our next pick!
