Thanks to everybody who helped me pick my “recommended” book! I wasn’t aware that we have such a large 今村 fan base here 
Based on your recommendations I have decided to read 木になった亜沙 | L27 as my bingo book (simply because it is the shorter one of the two top ones 
)
There is also an informal reading club for it: 木になった亜紗 Informal Reading Club which I will make use of.
Haven’t read either of them so far, unfortunately, but maybe somebody else knows more?
I was thinking that we could maybe run a little informal book club on とんこつQ&A | L26 next year if there is enough interest. For those who plan to participate in the 2026 bingo, I’m sure we can find a bingo square to put it in
