I pre-ordered the book long ago but after hearing John Green read the first chapter, I'm dying to get my hands on the actual book of TFiOS. The book is both serious and funny, it describes real feelings for young people who lives a hard life and you see all these things in the first chapter. You can't help but love Hazel, Augustus and Isaac and you can't help but get even more eager to get TFiOS and start reading the whole story.
I agree with Sarah: THIS WILL CONVINCE YOU. John: thanks for the reading.
