I have over 200 chapters in my book. (I will split the book since it is too big). Each chapter, with few exceptions, spotlights a different character. At the end, 161 different people have had a chapter centered around them and the story in general doesn’t focus on anyone but rather in a series of events that affect many, different people (as you can tell). Do you consider those people main characters? Would a book like this work out for you?
