From left to right, the main characters in the book are Steven, Jeffery, Renee, Annette, and Steven's parents. This book is written by Jordan Sonnenblick.
Steven woke up early one day, so he decided to go downstairs and play the drums. Jeffery later snuck up on him and scared Steven. After that, Steven made Jeffery oatmeal, and Jeffery fell off a big chair, got a huge nosebleed, and went to the emergency room. In the ER, Jeffery was diagnosed with Leukemia.
Every month, Jeffery had to go to a Philadelphia to a hospital. His mom had to leave work to take care of him every day. As the winter passed through, Steven got the flu, and because of Jeffery, he could not be home, so he had to stay with his grandparents. He stayed there until he got better, and it was boring while he was sick.
Since Steven's family is deep in debt, Renee and Annette made a plan to make the concert for his family to raise money. Meanwhile, Steven's mom is sick and so Steven, his dad, and Jeffery have to go to Philadelphia. There, Steven meets a girl who also has Leukemia named Samantha. They talked for a long time, until they couldn't anymore.
During the big concert for his family, Jeffery got sick and they all had to rush to the hospital. They ended up finding out that it was only an ear infection, but when he was there, he found out Samantha died.
In the end of the book, Steven wins the music award for his school. He mentions that he sees hair on Jeffery, so he might be cancer free.
