12-year old Edward is the sole survivor of a plane crash that kills his parents and his brother. The book starts off in the hours before the plane takes off, as we are introduced to Edward and his family, as well as other people who boarded the same plane. At first it feels a little bit pointless, getting to know all these people who are going to die. It gets more interesting once the book starts switching back and forth between Edward's life in the years after the crash, and the moments leading up to the crash itself.
Ultimately it's a book about survivor's guilt and surviving the loss of your entire family. I felt it reached a quite satisfying conclusion, as well.
