This is a historical novel about a small group of scholars (mostly of color) in Oxford in the 1830's, with an added fantastical element of magical silver powered by language and translations. Historically, it covers a modified industrial revolution, British colonialism, opium wars with China, and even gets into the Luddites, all impacted and warped by the British empire being powered by silver. What I especially appreciated is that the magic silver mostly just exacerbated issues and functioned as a metaphor for power in all of these historical situations; this is not a book about historical divergence due to magic but rather a book where the magic is used as a metaphor to reexamine things in a fresh light.

The idea of magic silver here powered by translations is just so well done. Scholars (and thus language) are extracted from colonies to power silver magic as a parallel to other resource extraction. The scholars are ultimately not really wanted for who they are but for the utility of what they know. And, I also love the detail that the empire is eating its own tail by its continual expansion and globalization weakening the magic. It reminds me a little of Yoon Ha Lee's Phoenix Extravagant where the magic system itself was intricately tied to colonial resource extraction.

It's a slow-building book that doesn't pull its punches about colonialism, racism, white folks siding with the establishment, or (as the subtitle to the book directly informs you) the necessity of violence. I enjoyed it quite a bit.
