The biggest challenge I'm seeing so far is how to get each POV character enough "screen time", if that makes sense. Since they are all taking place in a three-kingdom battle I'm struggling with how and when to switch between each POV character.
Up until now, each chapter of the book focused on one POV character. When I switched to another POV character, I started a new chapter. Having everyone involved in the same battle - some of the POV characters are actually together and others are doing their own things - makes giving each his/her own chapter just won't work.
Unless my chapters suddenly go from a few thousand words to barely a thousand.
My only other choice is to break down and start switching between POV characters within the same chapter.
Then again, a third option is to very tightly plot the battle when I get to the rewrite in such a way that I can have regular length chapters while not impacting the intensity of the overall scene, while managing to give each POV character their due.
Whichever way I end up going, it will be complicated by at least one of these POV characters getting killed off during the battle.
Considering the multi-volume epic fantasy story I want to write will have upwards of 10 POV characters, working through this process should prove quite fruitful later on.
ETA: I thought I should add I'm working with 5 POV characters here during the climactic scene. And, I've been thinking of possibly making another of the characters present a POV character whenever I get around to rewriting this thing.
