Someone is plotting to put all gargoyles in jail . . . or six feet in the ground.
For decades gargoyles have patrolled the night in Montreal Ward. They are dubbed Guardians by the humans and fae who live on the fringes of society, those who survive in neighborhoods the police don't care about.
But when a Guardian is accused of murder, their reputation blackens. Mason promised to return from France with the one weapon capable of killing the formidable witch who was reborn from the bloodstone, but no one has heard from him in months.
Now Polina gathers forces. Without Mason or the Guardians, Kyra has no backup as she tries to solve a murder and face off against new and terrifying monsters . . . all while caring for her growing menagerie of extraordinary critters.
