Return to Kat Howard’s Alex Award–winning world begun in An Unkindness of Magicians, a secret society of power-hungry magicians in New York City. After taking down the source of the corruption of the Unseen World, Sydney is left with almost no magical ability. Feeling estranged from herself, she is determined to find a way back to her status as one of the world’s most dangerous magicians. Unfortunately, she needs to do this quickly: the House of Shadows, the hell on earth that shaped her into who she was, the place she sacrificed everything to destroy, is rebuilding itself. “The House of Shadows sits on bones. All of the sacrifices, all of the magicians who died in Shadows, they’re buried beneath the foundations. Bones hold magic.” The magic of the Unseen World is acting strangely, faltering, bleeding out from the edges. Determined to keep the House of Shadows from returning to power and to defeat the magicians who want nothing more than to have it back, Sydney turns to extremes in a desperate attempt to regain her sacrificed magic. She is forced to decide what she will give up and what she will lose and whether what must be destroyed is not only the House of Shadows, but the Unseen World itself. World Fantasy Award finalist Kat Howard has written a sequel that asks how you have a happily ever in a world that doesn’t want it, where the cost of that happiness may be too much to bear.
