This is one of those books that leaves you in a depressed daze for a few minutes after you finish reading it, like: O_O wowwww ... It was really sad. BUT it had an original and compelling premise, and it was written in an interesting way. Also, I think the topic of teenage suicide – and how it can be prevented – was really important. But, the characters could have been stronger. Hannah came off as rather whiney and selfish, so unfortunately I didn't feel much sympathy for her.
