Another great addition to the Avatar universe.
I am once again saddened to finish such a great read. At least after finishing the first book, I had the second one to look forward to. It's possible due to the content of the epilogue there could be a third book in the works, but I think that's just wishful thinking on my part. After all, I expected there to be a lot more Kyoshi x Rangi, considering the cover of the book. (And the fact that I assumed Rangi was the titular "Shadow of Kyoshi.")
I'm a sucker for LGBT+ and seeing Kyoshi and Rangi together always warmed my heart. I know that this book (and even series) isn't a romance series, so not focusing entirely on their romantic relationship is fine, but I wouldn't object to more. That being said, their relationship, apart from the romantic side, is a pleasure to read. They work so well together. A true bending duo.
I also want to point out that the formatting (of both this one and the first book) is on point. Absolutely loved it. Helped with the experience of the read.
That all being said, I did feel like the writing was slightly different than the first book, despite knowing it was written by the same person. Maybe it's because it's been a few months since I read the first book and I'm just not recalling it, but it feels different. I mean, not so different as to feel like a different person is writing book two, just, different. I'm unsure how to explain it.
Also, there were a few times where the POV would switch slightly and that was a bit distracting. Like a small line or two stating stuff Kyoshi (or whoever had the POV) shouldn't know. I mean, she could totally guess judging by the context, but it wasn't worded like a guess.
Overall, a fantastic read and a great action story. A worthy addition to the Avatar universe. If you love Avatar, you for sure have to check this out. And even if you don't know anything about the universe, reading both books should help you in that regard. No need to have seen the show. (Though I recommend that, too).
