This is Not My Hat
by Jon Klassen
Oh my goodness! What a story! Twists and turns I never expected!
There's a cute little fish. And he has a cute little hat. But it is not his hat. He has questionable morals. He stole it from a giant fish. Who wants it back. Only the little fish doesn't realize it. He's sure the hat won't be missed. Or, if it is, the big fish won't come after him. Or, if it does, the big fish won't catch him. But... well... you can see where this is going! It's described on Amazon.com as "deadpan-funny," which is so accurate. It's dark and charming all at once.
