Lark's back in the City
Back working as sheriff for the Library.
Back from his time out with the ghosts. Aware now of who's behind the last few years of hell. Bernadette, daughter of the Old Man, the cruelest, strongest sorcerer Lark ever went up against.
Back, but not without wounds. His head ain't what is used to be, demon scars riddling his brain and soul. And the Library has enemies where allies were, no-one knows who's who, and friends are thin on the ground.
Then the killings start. High profile, ritual magicians are dying. Ancient Egyptian death magic is being toyed with, and sorting that mess out falls squarely on the already struggling Lark. There's a profound crime happening, a plot a century in the making. And Lark is standing dead centre.
