This entire post will be a spoiler alert so if you don't want to know, don't read it.
The thing about John Green is that he writes all these beautiful words and makes you fall in love and then he takes it away in the most beautiful way he can imagine and you're left there wondering what the hell happened and how you got so involved in something that you were just reading. Even though it's sad, it's still funny and there's a sense of normality to it. He adds humour to make it okay that something really bad has just happened.
The Fault in Our Stars is about a group of young adults who have different kinds of cancer and they go to a cancer support group. It's at this support group that a girl finds a boy and they fall in love. It's all very tragic because they know that their time might be up. So they make the best of what they've got. Then it's all about probabilities and time. And in a likelihood to survive in an 80-20, you'd think you were in the 80% side, then you're not. Then you realise that John Green's right, "Time is a slut, she screws everybody."
If you read this book, prepare for a rocky ride. Bring tissues. Don't fall in love with the characters.
Just when you think everything is okay, it isn't.
