So one of my MCs dies in the sequel due to injuries and complications. Wondering if it would be an option to fill the MCs spot with a strong secondary character, or just leave the spot empty? One small problem I have is that I have been told the MC is likable. It would be consistent with the 'no one is immortal' theme in their fictional universe, but is it ok to fill the dead characters spot? FYI they would die within the first 30 pages, so it is not like I am pulling a death and switch at the end. Trying to keep it early on. What are your thoughts, and thanks for your opinions and ideas.
