The Fault in Our Stars is an improbable story, but it doesn't feel like one when you're reading it. It feels exactly right.
Maybe it resonates so strongly because of my life as a sick child and then a sick adult who lost most of her sick friends in childhood. Our lives were more predictable because we didn't have cancer, which is unpredictable pretty much all the time, but we were still surprised sometimes. We loved each other and sometimes we fell in love and once in a while the person who died was the one who wasn't supposed to.
What I'm getting at is that it's really weird being a kid and having a mental list of which friends are supposed to die first. Green captures that feeling, all of those feelings, better than anyone I've read who wasn't somehow one of us. I was sure that he had lost a child or a sibling to cancer, right up the point in the acknowledgements where he says he didn't. It's that good.
So it's also that bad. I felt Hazel's pain and joy and fear so completely it was frightening, even as I was jealous of her strength. Hazel is a beautiful creature, as is Augustus, and their love is a privilege to witness.
Bonus points to Green for making up a book for them to bond over rather than using an existing one and turning it into a half-assed lit class. That was a real stroke of genius and made their world all the more real for being wholly fictional.
