I felt the beginning of this book was very sad because the main
character, Miho's parents died. The sadness was stressed all
throughout the book but it faded away as Miho received the power
to talk to dolphins, the power to ride the sound of a whale, and
many other powers. I learned about how water pollution and the
annual Japanese dolphin hunt harm the dolphin population. The
Gaia Girls series is very interesting because it is both fiction and
something that helps you learn about the environment.
