For my new manuscript, I've been following a different course than usual. Typically I allow my characters to create their own arc and the story develops around that. But given the nature of the story I've chosen to tell this time, I decided to adhere to the classical three act structure. The first act being exposition and establishing the world until a dynamic incident occurs to set up the second act where the character attempts to deal with the situation, concluding in the third act.
In the past I've tried to avoid a strict interpretation of this natural unfolding of events. I've always enjoyed a fluid story that can overlap acts in interesting ways. But there are certain types of stories that are just tailored made for the established rules. Having moved into the second act, I feel as though this current tale is one of them. A big part of writing is not only having a good story, but knowing the best way to tell it.
