Many people belong to book clubs. Some are formed when a group of friends decide to meet regularly to discuss a book they’ve chosen.
Some clubs are organized by librarians and some by organizations looking for activities for their members.
Books are often chosen by members, but not necessarily. For example, the leader might pick out a book he/she liked then put that on the list. No discussion or chosing required.
Meetings can go smoothly with all participants following established guidelines. Others have a harder time, especially when one member decides to hijack the discussion and turn it into their own topic, such as scams or relatives.
Your task is to write a story in which a book club plays a prominent role. If you write mystery, a death might occur that the members, along with the police, investigate. Or perhaps a fight breaks out, either verbal or physical. Not all members will like the book, and to develop tension, a heated discussion might ensue.
This calls for lots of dialogue. Description is important as well so that readers understand the scene, the participants and the relationships.
Have fun with this one.
