Harbinger of Justice

The Harbinger of Justice has a fast-moving plot but still takes time to develop the characters without derailing the pacing. The setting of the world being a desert is very interesting and refreshing (day-night cycle in the desert). The world-building in this book is absolutely phenomenal. The shadow magic system is creepy and intriguing.
The characters are truly fascinating. They are deep, intriguing, and have their own lives. They feel very fleshed out, even side characters. Rai and Fax's duet works very well. They can be serious one moment and funny a moment later, especially Fax. Though, some characters could have been utilized more and better, for example Kyan.
The only part that felt a little out of place was the plot in the library. It does not feel like it added a more to the plot, especially that a few chapters later (being a climax of the story) a very similar plotline happens again.
The story is intriguing, and for now, this book really helps to set up the world for the next adventures.
Overall, Harbinger of Justice is a must-read. The writing style is very accessible, and the pacing is good. The book is a page-turner that will keep you engaged from beginning to end.
