First love can be true love - and this is one of those books. It's really a book about two teens who are too wise and philosophical for their age. Perhaps, that's because they're terminally ill. Perhaps, it's because they're John Green characters (who are all too smart and philosophical, but in the BEST POSSIBLE WAY). Perhaps, people like this really exist.
It's a funny book about a girl with cancer. Or it's a book about teens who despise the Kids With Cancer cliche and make jokes about the misuse of the word literally. No - it's a hilarious and heartbreaking book about the self-proclaimed King of Cancervania who is too gorgeous to exist.
How can I sell you on a book about cancer?
Just read it.
