I'm reminded of Chester books when I read this one. A girl and a boy are asked to write a story together. They differ on how the story should unfold and their conversation is included in the narration. You could include this book in a lesson perspective or point of view. She wants the story to be girly, he can't stand the girliness and wants there to be motorcycle dudes and gross stinky giants. It would make an interesting discussion on gender roles as well.
The illustrations in this book are dazzling. Kids will love this one!
