An Education in Longing by Charlotte Stein

A darkly sexy romance about a young woman attending an enchanted school, who must defeat a malevolent force only through accessing a very powerful magic... one that’s rooted in her sexual desire.

When Mina manages to pass The Test and gain entry to a university that reveals a world of magic just beyond ours, she’s determined to go and prove her worth. But Harrowhall is full of dangers untold, and hardships unnumbered. And every one of them seems designed for only the privileged to pass. If she has any hope of becoming the witch she longs to be, she’s going to have to rely on the last person she wants to: Harker St James, the most lethal student to ever walk those haunted halls.

And once she unearths his dark secret, she has the means to persuade him. Not to mention a way to keep him at bay. Because Harker isn’t just the key to her salvation. He’s the deadly snare that daily threatens to drag her down. Desire fires her magic, but any feeling for him is a poison she simply can’t afford. 

Even though the fate of Harrowhall, and the magic it was built on, may very well depend on doing all the things she really shouldn’t.
