Applegate's book, The One and Only Ivan focuses on Ivan, a gorilla living in a mall arcade, while Klassen's book, This is Not My Hat follows a little fish wearing someone else's hat. If you've read Klassen's 2011 book I Want My Hat Back, a cute bear missing his hat with a bloodthirsty ending, you won't be too surprised by how this one ends.
A special congratulations to Candlewick, Klassen's publisher (as well as TOON's).
