The
inner story of a book is the transformation of a person, the main
character or narrator, through a series of outer events. This is called
a narrative arc. Without this narrative arc, a book is just like
reading a list of crises.
Readers want to witness growth. The narrative arc is the journey of growth. A clear narrative arc makes a book feel cohesive. But since narrative arcs are about change, the character's journey often starts with something they don't understand. Something they are challenged by. Another way to look at this: it starts with a false agreement.
