Second paragraph of third chapter:

Kenning was right underneath their new visitor. What was she doing?

Emily Tesh again shows her extraordinary versatility, with a story of a queer teacher in charge of safeguarding vulnerable pupils at a magical boarding school against dark forces while securing her own back against bureaucratic enemies. This is contemporary Britain, but with demons and a professional structure for the magically talented people who control them; it’s also a Britain where our friends class and race are alive and well, especially in a school where some of the scholarship pupils are also orphans. There’s cracking emotional chemistry as well between Sapphire Walden, the damaged but still idealistic protagonist, and her love interests; and finely observed dynamics of how a small group of gifted teenagers interact with the outside world.

It’s brilliant stuff, and really it makes you realize how few of the well-known magic school stories, from Roke to Hogwarts to the Scholomance, tell the story from the viewpoint of the teachers rather than the pupils. (There’s Unseen University in Discworld, but it’s a third-level institution rather than school and it also seems to have very few students.) Of course there’s always mileage in a rite-of-passage story, but the children’s point of view sees only the part of the educational iceberg that is above the surface. If you see what I mean.

Anyway, you can get The Incandescent here, and you should.
