This book is a perfect addition to the avatar universe. Kyoshi has a great journey as she comes into herself as the avatar. She's allowed to be violent and chaotic. She's very bi. She does crimes. She has a flying bison and a Fire Nation girlfriend and war fans.

I loved how morally grey all of the characters were in general. Everyone does bad things and ends up in complicated situations. I also loved what the characters did with bending, especially earthbending. There was so much fascinating innovation and experimentation.

Anyway, you should definitely read this book if you like this universe!
