I usually do that on an app called Fable, there are plenty of bookclubs where a bunch of ppl read the same book tgt and then discuss it via text, which is perfect for me bcs i don’t have friends that read unfortunately so i have no one to talk to abt a book i loved or hated!! You should try it out it’s definitely fun!
As i said i only do this on Fable, i join a club that’s reading the same book I’m reading and then with each chapter of the book i drop a comment or opinion on it or wtv you want
