So, yep. Five stars. 
 The writing style is fluid and impeccable, and, being a huge David Levithan fan, I can now see how they would fit together so perfectly. Please excuse me while I run off to read Will Grayson, Will Grayson. 
 I listened to this as an audiobook, and I think it's the first book EVER that I truly loved listening to. The narrator was brilliant, and didn't lower her voice trying to make the male characters manly. You're a woman! I won't fault you if you can't sound like a man! 
 A friend of mine had a discussion before I read this book. She doesn't believe in cancer for entertainment value. I completely agree with her. But this book isn't about cancer. It's a tragic love story, and the characters just happen to be sick. Heavy emphasis on the tragic. Way to crush my spirit, John Green. How do you sleep at night? The only thing that could have destroyed me more would have been to end it halfway through the last sentence.
