Before I Fall- Characters

In the book Before I Fall, the main character is telling the story of how she died, and how she spent her last day alive. In the beginning, she does not seem very serious about the fact that she had died, and doesn't even seem sad. But as the story goes on, she tells what happened and how she has one day to live left. I think as the story goes on Sam, the main character tries to figure out what to do and how to stop the future from happening. She relives the same day and tries to figure out what to do, and how to stop a huge accident. She gets into trouble, at the same time of this and tries to avoid even more. In the beginning of the book, she didn't care about what she did with her friends, and she didn't really seem to care about herself, much either. But after that, she tries to make things right again, and save herself even though she is doubtful of that. Based on this I think Sam will seem to be a laid-back, careless, teenager who doesn't really care about a lot, but I do think she will change her ways toward the end of the story. I think this will advance the plot because I think she will try to avoid the mistake from happening over and over, and try to be a better person, in general.
