In this final book of the graphic novel trilogy, Kaidu and Rat are trying to recover the lost secret weapon of the ancient people of the Nameless City - a formula for exploding fire. They think it will be easy to sneak into the palace and steal back the book containing the formula; after all, they have snuck in and out of the palace many times before. But their only route past the walls has been demolished, and they will have to find some other way to get past the guards and into the inner library. Meanwhile Kaidu's father is trying to reach the other nations and gather military support to take back the city from the traitors among the Dao.

I loved these characters so much! Kaidu and Rat have so many emotional scars, but they find strength and support in their friendship. They have to trust each other absolutely through their adventures. No matter what other cultural or political changes may come up, these two remain loyal to each other, open to listen and respect their differences.

The plot is fantastic and imaginative! Kaidu and Rat get into lots of mischief and dangerous adventures. You get a sense of the depth of the characters and the history of the city. They have to decide what the future of the Nameless City is going to look like, but still respect its past history.

In this third book, we see Rat begin to lay aside her sad past and heal those old emotional wounds. She has to let go of her anger and grief, and learn to live beyond her limited perspective. She has a vision of what the city could be like in the future where people of all nations could live in harmony together. It is that vision that gives her strength to endure.

I love the world building. This book answers some of the questions about the ancient people who first built the city. Now that Kaidu and Rat know the mystery of the secret weapon the ancient people developed, they have to decide what to do with it. It was intriguing to see how the political landscape keeps changing as the nations come together to decide the fate of the city. There are many different cultures that are not blending very well due to prejudices and political unrest, but the friendship between two young people might just be the answer. Kaidu and Rat are determined to protect the city and each other.

The artwork is excellent, and every page is colorful and full of energy! This is such a satisfying end for a great trilogy!
