My usual gripes about criminality in this series aside (and in the acknowledgements she does go into talking a little bit about her sources in terms of criminal justice techniques, especially about The Mind of the Pathological Criminal, so I was right, thank you everyone) this maybe was my favorite one? Though I am uh Wary of Fantasy India's Caste Systems (and the Chekov's lowest caste) but I am not super qualified to comment there. 

All that said, I did love the character relationships; it feels like Tris's apprentice was so beautifully constructed to clash with her in the most perfect ways, and to watch her grow and appreciate her being Mean but also so deeply kind and determined to stick to her obligations. Keth was such a great foil, it was fun having some more disabled representation in the series, and the magic stuff was super cool to watch unfold. It made me want more with him, and I'm excited to see what happens in the next series!
