There is nothing more refreshing than a book that is truly completely new. And this is: Clark imagines a Cairo in which the late industrial revolution was marked by the emergence of djinn and magic. And rather than handle this as a fantastical event, the world simply adapts to this as a newfangled technology: you know, kids run off to the continent to take "alchemical classes" and in my day, high-bred kids just took Latin. And by the way, the steampunk aerial trams are also powered by magic.

Mix this with a strong sense of place: Cairo here is presented as a melting pot of Western Asian, Middle East and African cultures. (Me: Is it Afrofuturism if it's set in Egypt? Jon: Is it about either Cairo or Alexandria being the best in Africa at something? Me: Cairo is the hub of the African dirigible system...so...yes). And then add in some bureaucratic procedural elements in the form of a pair of police officers whose job is to take in magical hijinks. Plus a heaping dose of suffragettes (the Egyptian feminist society in this alternate history gaining a much early right to vote) and the result is completely delightful.

This book is SHORT -- most novella's feel short because there isn't enough space to develop an interesting set of characters/plot/setting, but Clark really excels here. Just to illustrate how quickly he sketches the scene for you, three pages in you know that the world has gone through a recent technical revolution, the main character is cynical because hauntings are too mundane and his partner is overly eager. Indeed, this novella feels short because there is so much developed and so many interesting questions like, should tram cars be emancipated? How are djinns similar and different from ethno-specific folklore beings? What rights do non-binary gendered beings have in this world? And while the story comes to a satisfying conclusion, these existential questions are unanswered. I hope Clark continues to write a lot in this setting.
