I pulled an all-nighter reading this book and now have a terrible book hangover, because I absolutely could not put it down and go to sleep until I knew why Hannah committed suicide. 13 Reasons Why is about a high school girl named Hannah who committed suicide. Before doing the deed, she recorded her story on 13 cassette tapes. Each tape revealed a new piece to the puzzle, another side of her story. On each tape she talked about a different person, and how that one person who may have done something insignificant, like writing her name on a "hot or not" list, or spreading rumors about a hot date; impacted her to the point where she felt that she had no other option. Right before she did the deed, she sent her tapes to the first person on her list. After listening to her story, they gave the tapes to the second person, and so on. The tapes ended up with Clay. A quiet boy who hardly knew Hannah, and he couldn't figure out how he had anything to do with her decision. This book really spoke to me because I believe in a ripple effect. I believe that as humans, our lives are weaved together in ways that we sometimes can't even imagine. I believe that an act of kindness can change someone's life forever and that a snide comment, even in if was not meant in a rude way or was just a joke, can cause a person to be bitter for years. I would recommend this book to anyone who has dealt with depression, or is currently going through it. This book will really change the way you look at life and how your decisions impact those around you. If you enjoyed this book, I would highly recommend "The Five People You Meet in Heaven" by Mitch Albom.
