Not a book to be read quickly. This must be savored. A 16-year old commits suicide and leaves his friend a playlist to discover why he committed suicide. Listen to the song at the beginning of each chapter and see how it fits. Listen more than once. Make sure you know what is being sung. I only knew one of the songs but found a lot of them I enjoyed. Listening caused me to read slower but I wanted to be able to put the clues together to figure it out as Sam (the friend) was figuring it out.
I liked Sam. Started out hating some of the characters while loving others I met throughout the story. The ending changed my feelings towards some of the characters but not all. Some are just jerks and you can't change that. Some seemed cool but had feet of clay. Others were hurt just as much by the popular kids but managed not to lose their integrity.
Read this book for the experience.
