Inej Ghafa never lived long enough to become a spider and refused to let Heleen, or her clients, be her downfall, so she dove into the harbor in search of death. Instead, she became a monster. Which, for a pious girl like Inej, is practically the same thing. Until Kaz Brekker comes along, and she learns the line between "monster" and "mortal" is a lot thinner than she believed.

One night Kaz Brekker finds Inej Ghafa inexplicably in his bed.
