Hank Hudson is in a bit of trouble. After an incident involving the boy's bathroom and a terribly sad book his teacher is forcing them to read, Hank is left with a week's suspension and a slightly charred hardcover--and, it turns out, the attention of new girl Maisie Huang.

 

Maisie has been on the lookout for a kid with the meatballs to help her with a very important mission: Saving her neighbor's dog, Booler. Booler has seizures, and his owner, Mr. Jorgensen, keeps him tied to a tree all day and night because of them. It's enough to make Hank even sadder than that book does--he has autism, and he knows what it's like to be treated poorly because of something that makes you different.

 

But different is not less. And Hank is willing to get into even more trouble to prove it. Soon he and Maisie are lying, brown-nosing, baking, and cow milking all in the name of saving Booler--but not everything is as it seems. Booler might not be the only one who needs saving. And being a hero can look a lot like being a friend.
