Dr. Walden is the Director of Magic at Chetwood Academy and one of the most powerful magicians in England. Her days consist of meetings, teaching A-Level Invocation to four talented, chaotic sixth formers, more meetings, and securing the school's boundaries from demonic incursions.

Walden is good at her job - no, Walden is great at her job. But demons are masters of manipulation. It's her responsibility to keep her school with its six hundred students and centuries-old legacy safe. But it's possible the entity Walden most needs to keep her school safe from-is herself.

'The grown-up answer to the magical boarding school tale . . . Every book Emily Tesh writes is a magic trick, and this is no exception: with one hand it delights and entertains you, and with the other it's slowly unfolding a set of huge feelings and ideas to illuminate the underside of your mind. Fantastic in every sense of the word'
Freya Marske, author of A Marvellous Light

'A searingly brilliant fantasy. This is magical school with teeth. Warm-hearted, terrifying and clever, Tesh's examination of magical school through the eyes of an unforgettable - and properly grown up - heroine is an unmissable read' Tasha Suri, author of The Jasmine Throne

'An absolute flex of a book, empathetic and passionate and deeply thoughtful. Above all, Tesh will make you care: about place, self, and the brave, impulsive, vulnerable, curious, incandescent young lives that are our future. A gorgeous evocation of what it means to have a calling'
Shelley Parker-Chan, author of She Who Became the Sun
