I've started a book series I've seen recommended here and there for a while, and it's really, really good
It's Naomi Novik's Schoolomance triology, I finished the first book yesterday, and have bought the next two. A deadly school for young magicians (and the deadliness makes sense in the world), and a protagonist who is destined to become an immensely powerful evil sorceress (if she tries to find a spell for creating a small light, the library gives her spells for firebombing a city). She is resisting as hard as she can, while being delightfully snarky about it all.
