I found this compulsively readable and stayed up late finishing it in two evenings. The narration effectively allows you to read Clay's reactions as he listens to the tapes, as he struggles to understand Hannah's depression and struggle to be heard. With my decades of hindsight on my teen years, I didn't quite feel that Hannah's explanations justified her suicide, but I still feel that the story clearly outlined how one person's small, seemingly inconsequential actions can have a major impact on someone else. Definitely a great book for teens and teen discussion groups.
