There’s so much to love about this book. If you are a fan of Avatar The Last Airbender, medieval Japan, or stories of superheroes, this is the book for you. There are several viewpoint characters that are all richly defined, unique, and grounded in the setting. The action is good, and moments of tension really pay off. But it is the relationship between all these characters and the way in which they shape each other that brings this book alive.
