This is the story of teenager Hannah Baker, who sends tapes to the people who are connected to the thirteen reasons why she commits suicide. A story about friendship, despair and the responsibility we have for our actions and how they influence other people. A story which shows us how important it is to prevent a classmate from becoming a loner. In Hannah's own words: "No one knows for certain how much impact they have on the lives of other people. Oftentimes we have no clue."
