In the exposition, Steven's passions for drumming were introduced very early in the book. He was shown to be one of the only 8th graders in the high school band. His Mom, Dad, and Jeffrey were also introduced.
Concert = Fundraiser
Jeffrey asked Steven for some "moatmeal" and Steven put Jeffrey on the stool even though he was told not to. Then Jeffrey fell of the stool resulting in a huge nose bleed. This caused Jeffrey to be hospitalized for many days.
Jeffrey went to the hospital and while he was there he was diagnosed with Leukemia. This terrible news affected the family in a very negative way and Stevens life started to fall apart. He started to fail his classes, he was starting to feel depressed and lonely, and his family and life at home jut wasn't the same.
Annette, Renee and Steven came up with the Idea of raising money for Jeffrey's hospital bills at the band concert.
Jeffreys condition started to cost the family lots of money, so after a long battle of back and forth opinions, Stevens parents finally allowed Steven to have a fundraiser for Jeffrey. The All City band decided to dedicate their concert to Jeffrey and his family. During the concert Jeffrey had an emergency and had to be rushed to the hospital. It turned out he only had an ear infection.
