Pete the Cat and HIs Magic Sunglasses is such a good book for young readers. I really love the whole Pete the Cat series. In this book, Pete is grumpy until he discovers some cool sunglasses that makes him suddenly feel positive and happy. When he runs into his other friends that are feeling down as well, he lets them try the magical sunglasses and they also become happy. I feel as if this book promotes sharing and helping friends out when they are sad. I would use this book anywhere from kindergarten to 2nd or 3rd grade.
