People need to change

Stories and novels have different paces, impetuses, and drivers. Some stories are all about characters evolving and others are about people surviving what is happening around them.

No matter what your story is about, however, readers will come for the characters. They want to know about people. They want to see themselves there. They want to feel some satisfaction for the characters when the story is over.

So, regardless of what action is happening in your story, you need to make sure that characters progress, change, and evolve. You have to make sure that characters are somewhere else at the end of the story. Not physically, but as humans.

You can make anything the focus of your story, but make sure that something happens to at least one of your characters along the way to change them. Your readers are waiting for it.
