I absolutely love this book. I have read it several times, and it always manages to make me cry even though I know the story. 
 I know there are some mixed reviews about it, because "You don't commit suicide because of reasons, it's a chemical unbalance in your brain," etc. 
 But here are some reasons why you should still give this book a try: 
 1. Originality. The audio tapes. Never has a story been explained in this way. 
 2. Extremely well written. The characters are diverse, and believeable. 
 3. Did I say diverse? Everyone is different- in the story and in real life. One person may commit suicide because of the chemical unbalance, making it hard for them to be happy. Another might do it because of circumstances. Reasons. 
 4. Many controversial topics. From Suicide to rape. This story shows these things happen but they can be prevented. Sometimes there are signs... and you never want to assume someone is in it for the attention. Always try to help, or notify an adult, or several, of the situation. 
 5. Even with these topics, it is still a work of fiction. Read it. It balances on the line of informative and entertaining (albeit in a somewhat sad, yet thoughtful way.) 
 I believe this would be a fantastic movie and I hope to see it on a big screen one day.
