As you will know if you read last week's book of the week I am a big fan of Jon Klassen's illustrations, so I was excited to see this new book a few weeks ago. "This is not my hat" is a book about a little fish who steals a hat from a big fish.
He knows it's wrong to steal a hat but he thinks he won't get caught. The trouble is, he does.
The book is beautifully illustrated, funny but with a serious message that stealing is wrong. And I love the ending and the different reactions and thoughts my children have about what happens to the little fish.
