Clay Jensen, a quiet, shy high school student, returns home from school one day to find a package from an anonymous person sitting on his doorstep. Upon opening it, he discovers that it is a shoe box containing seven cassette tapes recorded by the late Hannah Baker, his classmate and emotionally damaged crush who recently committed suicide by taking a handful of pills. The tapes were initially mailed to one classmate with instructions to pass them from one student to another, in the style of a chain letter, starting from the one involved in the first story to the last. On the tapes, Hannah explains to twelve people how they played a role in her death, by giving thirteen reasons explaining why she took her life. Hannah has given a second set of tapes to one of their classmates, the identity of whom Clay later discovers, and warns the people on the tapes that if they do not pass them on, the second set will be leaked to the entire student body.
