This book, along with The Fault In Our Stars (which I recently finished), is a great representation of the way a young adult book should be. The book is not about vampires or teenagers fighting for their lives or the lives of their districts. The book is about teenagers as they navigate through life.
The reason, I feel, the book appeals to young adults and adults alike is because the characters described in the book and the events and emotions that they experience are familiar to young adults and adults alike as well. Who doesn’t know what it feels like to go to a party and feel unnoticed? There is one really well written scene where the main character, Charlie, exclaims that he feels “infinite” at that very moment and that, essentially, everything feels right.
