In a world where witches are hunted by the church, Louise le Blanc, who fled her coven for the city of Cesarine, is forced into marriage with Reid Diggory, a church huntsman.
A follow-up to the best-selling Serpent & Dove finds fugitives Lou, Reid, Coco and Ansel splitting up to recruit allies against the Dames Blanches, an effort that is complicated by Morgane's lethal game of cat and mouse.
