Clay Jensen returns home to find a strange package with his name on it. Inside he discovers several cassette tapes recorded by Hannah Baker – his classmate and first love – who committed suicide two weeks earlier.

All through the night, Clay keeps listening – and what he discovers changes his life... forever.
