The Evil Princess vs. the Brave Knight (Book 1) strikes me as The Pain and the Great One for the 21st century.
The Evil Princess and The Brave Knight are two siblings who do not always get along. And with the talents of sibling team Jennifer and Matthew Holm, one creative funny story about brothers and sisters comes about. I am assuming this story might be “close to home” for the author and illustrator. Or in other words, they are the inspiration for said siblings.
Evil Princesses trip Brave Knights. And when Brave Knights get hurt, the Magic Mirror is not amused. Yet, the two learn that having your subjects fear you or fighting monsters can get boring when you are alone in your room. When they agree to play nicely, the Magic Mirror lets them try again. But when rescuing a damsel in distress (who was not so much in distress as sleeping comfortably on the bathroom shelf over the bathtub) goes wrong, one major mess and a not so surprise ending occur!
What really makes this story fun are the amusing images (watch for a poor, put-upon kitty) and its relatable text especially with the modern use of the Sister being the Evil one and the Brother the Brave. Of course, there are still traditional gender roles are used (girl = princess; boy = knight).
This is a story that almost every sibling has faced at least once. And a story all-too-familiar to most parents. Most likely this a good one-on-one read with your own evil princesses and brave knights rather than a group setting read-along.
