This is not just a charming story about marine ecology. Through a child’s innocent eyes and genuine words, it gradually reveals the mentality of economic dominance in the adult world. Childlike language has a greater effect upon society than harsh criticism. The dialogue in the book is filled with compassion and understanding to make readers ponder over and over again. As islanders living in a place surrounded by the sea, we should care more about all the marine lives and sincerely treat them well. Let the critically endangered white dolphins leap freely once more and create the most beautiful waves in the ocean. This is not merely a wish for the young, but for all.
