The setting in this book doesn’t really affect the mood. The setting is pretty much only at his house and his school, which doesn’t affect the sadness of the story. The thing that affected the mood was Jeffrey, Stevens little brother, he gets cancer, and make the mood sad. This changes Steven, and everything he does like, his homework, his friends, and many other things. If Jeffery didn’t get leukemia, the mood wouldn’t be sad, but he did. And because the setting is only at his house and school, it just keeps it the same because nothing at his school or house really affects what he feels.
