Protagonist

The protagonist in my novel comes from heaven to try and win the pageant. She died on the way to her last pageant. She ends up winning the pageant, but at the end she walks out and then just disappears and leaves the crowd, parents, and the whole crew. Maybe, she was suppose to leave shock or scarce upon them. It could have been to bring the thought of whether ghost are real or not? Her role could have been to bring a change in the way the people look at the world, what's real and what's fake. I feel her role was to come back and win, but to also leave an impact on the pageant and girls. The biggest question I have is, is Samantha (the ghost) going to come to the next pageant? What was her role, like why was she sent? How is the book going to end up at the end? How are the people going to react to the whole seeing a ghost, and if they're going to believe it?
