I love this whole amazing magical series! Tui T Sutherland had managed to make the best books in the world!
If you didn't know this book is based on Qibli's perspective. You meet his family and understand more about him and his life including his crush on Moon. (Pretty sad) He helps his friends stop the prophecy, and defeat Darkstalker with a bit of animus magic in a really weird way. (But also kind of cute) (you will see what I mean)
