Since fleeing the gilded halls of Evergarden for the muck-filled canals of the Marshes, Marlow Briggs has made a name for herself as the best godsdamn cursebreaker in Caraza City. But no matter how many cases she solves, she is still haunted by the mystery of her mother’s disappearance. When Adrius Falcrest, Marlow's old friend and scion of one of Caraza's most affluent spell-making families, asks her to help break a life-threatening curse, Marlow wants nothing to do with the boy who spurned her a year ago. But a new lead in her mother’s case makes Marlow realize that the only way to get the answers she desperately seeks is to help Adrius and return to Evergarden society—even if it means suffering through a fake love affair with him to avoid drawing suspicion from the conniving Five Families. As the investigation draws Marlow into a web of deadly secrets and powerful enemies, a shocking truth emerges: Adrius’s curse and her mother’s disappearance may just be clues to an even larger mystery, one that could unravel the very foundations of Caraza and magic itself.
