All sorcerers are evil. Elisabeth has known that as long as she has known anything. Raised as a foundling in one of Austermeer’s Great Libraries, Elisabeth has grown up among the tools of sorcery - magical grimoires that whisper on shelves and rattle beneath iron chains. If provoked, they transform into grotesque monsters of ink and leather. She hopes to become a warden, charged with protecting the kingdom from their power. Then an act of sabotage releases the library’s most dangerous grimoire.

The five most dangerous liars in the land have been mysteriously summoned to work together for a single objective: to kill the god king Joon. He has it coming. Under his merciless immortal hand, the nobles flourish, while the poor and innocent are imprisoned, ruined … or sold. And now each of the five blades will come for him. Each has tasted bitterness—from the hired hit man seeking atonement, a lovely assassin who seeks freedom, or even the prince banished for his cruel crimes.

Isobel is a prodigy portrait artist with a dangerous set of clients: the sinister fair folk, immortal creatures who cannot bake bread, weave cloth, or put a pen to paper without crumbling to dust.

Artemisia is training to be a Gray Sister, a nun who cleanses the bodies of the deceased so that their souls can pass on; otherwise, they will rise as ravenous, hungry spirits. She would rather deal with the dead than the living, who whisper about her scarred hands and troubled past. When her convent is attacked by possessed soldiers, Artemisia defends it by awakening an ancient spirit bound to a saint’s relic. It is a revenant, a malevolent being whose extraordinary power almost consumes her - but death has come, and only a vespertine has any chance of stopping it.
