Finished this over Vacation and I LOVED IT! I'm officially giving this a 5/5 star even though I tweeted it was a 4.5 after finishing it. I really loved this story and all it's strange quirks. I think it really captured the reality of cancer and what it can do to the person and the people around them, but it was also really funny. I also loved the totally-not-perfect main character and his personality. Watching his life suddenly unravel around his un-friend's sickness and how it effects him.
I just think this is a really great book, and definitely worth the read.

PS it's nothing like TFIOS. Literally, I can't believe people are comparing them.
