Urban fantasy places the supernatural inside a contemporary, usually urban setting that the reader recognises. Its defining structural question is the relationship between the magical order and ordinary life: concealed, openly integrated, or actively contested. That choice determines almost everything else — a hidden world generates investigation and secrecy plots, an integrated one generates politics and civil-rights plots, and mixing them without deciding produces a setting whose rules the reader cannot hold.
Also written as contemporary fantasy.
Decide the masquerade first
If the supernatural is hidden, the book owes an explanation for how, and that mechanism becomes a recurring source of both plot and comedy. If it is public, the book owes an account of how institutions adapted — policing, insurance, employment, religion. The unreliable middle is a world where concealment is asserted but never costs anyone anything, which readers of the category notice immediately because the masquerade is where most of its plots come from.
The city is a character or it is set dressing
The strongest work in the category is specific to a place: its neighbourhoods, its history, its class geography. Generic urban settings waste the genre's main advantage, which is that the reader already knows what a bus, a warrant or a rent increase means and the supernatural can be measured against it.
Series architecture from book one
The category is overwhelmingly series-driven, and first books are acquired partly on whether the premise generates more cases. That means a protagonist with a repeatable reason to encounter the supernatural — a job, a debt, an office — rather than a one-off destiny, and a supporting cast with threads left deliberately open.
Where to see it working
Rivers of London — Ben Aaronovitch
Police work supplies the repeatable engine, and the city's specific geography and history are load-bearing rather than decorative.
Neverwhere — Neil Gaiman
A concealed order with a clear and costly relationship to the ordinary city above it.
The City We Became — N. K. Jemisin
Takes the city-as-character convention literally and derives the plot from it.
How it goes wrong
Asserting a masquerade that never costs anyone anything to maintain.
Using a generic city, which discards the genre's main advantage.
Building the premise on a one-off destiny in a category that acquires on series potential.
Mixing hidden and public supernatural orders without deciding which the world runs on.
