Oh, how I LOVE the humor. The chemistry between Hazel en Augustus is awesome! 
 Little spoilers ahead! 
 I hated that Hazel and Augustus had such a short time together. I wished for more, because I love their converstations. But it is like that in real life too. You don't always get the time you want with a person. 
 Love how they describe Amsterdam and that it is such a big part of the book. I go there very often, so loved to read about the Dutch people and their weird way of talking for example or the way they ride their bikes. 
 Felt really unfair that Hazel did not get her answers in the end, but loved the ending with the letter from Augustus. 
 Book made me sad, made me cry a little, made me laugh out loud sometimes, wich made some people look weird at me... 
 I just wanted more of their conversations and them being together, maybe that is the way Hazel felt too...
