I just finished this book in less than two days after both laughing and crying. When I heard that John Green had released a new book, I immediately had to go to Barnes and Noble to get it, and it did not disappoint. This is the first time he has written from a girl's perspective, but he does so hysterically yet realistically. Without his trademark sense of humor, this could have simply been a depressing book, but with it, it's almost... optimistic?
Even though the book is not really violent, I can't think of how else to describe the fact that it may upset sensitive readers with its not so much graphic as simply intimate description of living and half-SPOILER (can't completely spoil it): knowing someone who dies of cancer. The one time the main character has sex with her boyfriend, it is not really described except for the fact that it is safe. There is language in this book, but it's not as harsh as Green's other books have been; language is about PG-13 level. The (teen) characters drink alcohol but don't really use it to drink to excess, unlike the author who Hazel (the main character) meets, but he is clearly not someone to look up to. Yes, the boyfriend (Augustus) does put cigarettes in his mouth, but does not smoke them. They are merely a metaphor, as he explains, for control over how he dies. Overall, this book was smart, funny, sad, and just plain awesome all at once. Unless you do not have a heart, you will be laughing and crying thoughout the whole book. DFTBA!
(Post-note: after I finished, I gave it to my mom to read, since I've been dropping TFiOS in any reasonable conversation, and she had to read it to see what all the "John Green this and John Green that" fuss was about. Though she took longer to finish it than I did, I knew it affected her as well. She read most of it on a field trip with a my brother on the bus, and when she came home she was sniffling a little bit, and the sniffling got louder as she got comfortable on the couch. When I asked her if something was wrong, she simply said, "I just about finished The Fault in Our Stars, and I..." and she trailed off a little bit. It was that good, for both teenagers and adults.)
