I have been in six book clubs. They were all different, and only some of them were really about books.
- The serious one. Everyone finishes the book and comes with notes. Good if you want to think hard.
- The social one. The book is an excuse for dinner. Lovely, as long as you know that going in.
- The genre one. Only crime, or only science fiction. Great for going deep.
- The library one. Free, open to anyone, and a good way to meet neighbours.
- The online one. Fits around any schedule, but easier to drift away from.
Ask the organiser what a typical evening looks like before you join. You will soon know which kind it is.
