Effy Sayre has always believed in fairy tales. Haunted by visions of the Fairy King since childhood, she’s had no choice. Her tattered copy of Angharad—Emrys Myrddin’s epic about a mortal girl who falls in love with the Fairy King, then destroys him—is the only thing keeping her afloat. So when Myrddin’s family announces a contest to redesign the late author’s estate, Effy feels certain it’s her destiny. But musty, decrepit Hiraeth Manor is an impossible task, and its residents are far from welcoming.

Inesa lives with her brother in a half-sunken town where they scrape by running a taxidermy shop. Unbeknownst to Inesa, their cruel and indolent mother has accrued an enormous debt—enough to qualify one of her children for Caerus’s livestreamed assassination spectacle: the Lamb’s Gauntlet. Melinoë is a Caerus assassin, trained to track and kill the sacrificial Lambs. The product of neural reconditioning and physiological alteration, she is a living weapon, known for her cold brutality and deadly beauty.

Alice Law has only ever had one goal: to become one of the brightest minds in the field of Magick.

Grimes is now in Hell, and she’s going in after him. Because his recommendation could hold her very future in his now incorporeal hands and even death is not going to stop the pursuit of her dreams….

Santo Domingo de la Calzada, 1532. London, 1827. Boston, 2019. Three young women, their bodies planted in the same soil, their stories tangling like roots. One grows high, and one grows deep, and one grows wild. And all of them grow teeth.

The Lady knows the stories: how her eyes induce madness in men. The Lady knows she will be wed to the Scottish brute, who does not leave his warrior ways behind when he comes to the marriage bed. The Lady knows his hostile, suspicious court will be a game of strategy, requiring all of her wiles and hidden witchcraft to survive. But the Lady does not know her husband has occult secrets of his own. She does not know that prophecy girds him like armor. She does not know that her magic is greater and more dangerous, and that it will threaten the order of the world.
