It was about half way through that I realized that this is probably the saddest fucking book I've read in a long long time. Carrie Mesrobian gets into the head of a character and owns that character. She makes you get into the head of that character and feel what that character feels, and Will? Well, he's a sad sad trainwreck of a boy. So sad. 
 I like how the author's note at the end says that we need to work for a world where it's easier for kids like him.
