The city has a protector from monsters: too bad she hates the job. She only gets things done because her familiar, a spiritual serpent she calls “S,” nags her to. But while she resists her duties, children mysteriously start dying in their beds with no sign of intruders. Finally pushed to investigate by her patron, the Lady, Addy makes a reckless mistake that nearly costs her life. Determined not to let her negligence allow more children to die, she uses every resource at her disposal to stop the monster from killing again.
