I have always wondered how you would kill a main character if the story is written in first person. Third person is understandable but hmm...
First person character watches other MC die. First person character cant die though. Then... well then you would need a new first person.
Actually debeting how i'm going to write the last book in my series based on a similar concept. All the MC's have to split up and kill different people states away. But they cant use cellphone or any form of technology to communicate with each other because the FRP will find them
