Ugh, so I hate the way the title is written. Also, I'm not sure I was in love with this book, but it was definitely a page turner. I had to keep going so I could see if I was wrong about it. Anyway, here's the summary.

When Clay Jenson plays the casette tapes he received in a mysterious package, he's surprised to hear the voice of dead classmate Hannah Baker. He's one of 13 people who receive Hannah's story, which details the circumstances that led to her suicide. Clay spends the rest of the day and long into the night listening to Hannah's voice and going to the locations she wants him to visit. The text alternates, sometimes quickly, between Hannah's voice (italicized) and Clay's thoughts as he listens to her words, which illuminate betrayals and secrets that demonstrate the consequences of even small actions. Hannah, herself, is not free from guilt, her own inaction having played a part in an accidental auto death and a rape. The message about how we treat one another, although sometimes heavy, makes for compelling reading.
