Oh My God. I don't even know where to begin! I've had this book for a long while, but I put it off because I knew it would make me cry. (Seriously, kids with cancer? How could I not cry?) I should have just sucked it up and read because it is so good. 
 I didn't just cry, I bawled. Almost uncontrollably. (Again, kids + cancer = crying, every time). 
 Despite all the crying that went on the book has some really funny moments and one liners. And there are a million quotes you could pull from this book. 
 Hazel was pretty awesome. She had some definite opinions and unique viewpoints on everything. I loved how she came across and how she defined things (she was a "Professional Sick Person"). She was cautious with her parents but also stood up to them when it was necessary. She tried so hard to be nice and kind to everyone. 
 Augustus was my absolute favorite. The way he talked to Hazel, sorry, Hazel Grace, the things he did for her. The way he just jumped into her life. They way their relationship developed. How he always tried to make everything better for her. 
 Hazel's parents made me tear up a lot. Their struggles and decisions, just everything. They were careful of everything that Hazel does, but also made some tough decisions to let her make her own. 
 No review would be complete without mentioning Isaac. Isaac goes through so much and Hazel and Augustus are at his side for most of it. 
 I was so involved in this book that I didn't even think, at all, about what might happen to Hazel and Augustus. It's that engrossing!
