I meant to reply sooner, but the afternoon got away from me and I only just sat down for a minute.
Yes, the book club idea sounds fun, and I do think keeping it casual will make it easier for everyone to join in without overthinking it.
My only suggestion is to pick shorter reads at first, because people always say they have time and then life becomes oddly busy.
I can help put together a simple list of options if that helps, maybe a mix of something light, something reflective, and something people can talk about without needing notes.
I am free most weeknights, though earlier works better for me because I lose steam late in the evening.
If you want, I can also handle the reminder message so nobody has to scramble at the last minute.
Either way, I am in, and I think it could be a nice routine.

I tried that new trail near the park this weekend, and it was much better than I expected once I found the correct entrance.
The first few minutes were a little confusing because the signs point in too many directions at once, but after that it opened up and felt really calm.
I think you would like it, especially if you go earlier in the day before it gets crowded with dog walkers and families.
I brought water, wore the old sneakers, and somehow still forgot a hat, which I regretted almost immediately.
Next time I want to take a small notebook because it felt like the sort of place where ideas arrive quietly and then disappear if I do not write them down.
If you are free next weekend, we could make a whole morning of it and then stop somewhere simple after just to sit and reset.
Let me know what day works best for you.
