AMAZING. I LOVED IT. Yangchen was so funny, smart, and cool. She had very unique struggles. She was so cool. I loved learning about Airbenders and their culture. Learning more about what the Airbenders meant as a whole and what their role was in the world really adds gravity to Aang being the Last Airbender. It also makes me hate Fire Lord Sozin even more. Wow was this book so much fun and well done.
