To continue the spin-off book club that started with すべてがFになる in this book club, we will probably read the next book in the series soon! For those who don’t know it: it’s about two amateur detectives who solve cases that involve maths, tech and engineering so there is some talking about these topics in the stories. It’s the third book in the series but I expect it to be readable without prior exposure to the series. We set up a poll for the start date so if you are interested, just raise your voice in there.
