3 ⭐ This book is an allegory for nap time. Harper is a little robot that is grouchy and causing problems. They need to recharge. Everyone knows they need to recharge except for Harper themselves. Harper refuses to recharge until they absolutely can‘t do anymore. And then realize that once they recharge, they feel completely better. This book is fine. The illustrations are quite fun. In fact, the illustrations are better than the story.
