A bookclub is not a class. For most people it’s an excuse to get together, have a drink and talk about a thing they like in a lightly structured manner. What OP is describing sounds more like a study group.
If I don’t like the book I don’t want to read it for months and months.
The 1-2 women that were actually serious about book analysis quit the book club.
One is exactly how you said, and the other had a host who a list of prepared questions and trivia to discuss, and pretty much goes down her list each time, and everyone gets a chance to answer each if they have anything.
I've found value in both types. I learn more from the latter, usually, but I enjoy the former, too.
I like the idea of a weekly club with partial book assignments, but that's more time than a lot of people are able (or willing) to give it.
