In a novel, the main character must go through a life-changing event that transforms them by end of the book. (For more read What Is Character Change and How to Create Character Change.) With that in mind, it should be easy to know who is my protagonist, right? Just build the novel around whoever has the biggest change to make! Except in my current WIP I’m not sure who that is. Both potential heroines will change by the end, but who should lead the story?
