From the New York Times bestselling author of Ninth House, Hell Bent, and creator of the Grishaverse series comes a highly anticipated historical fantasy set during the Spanish Golden Age In a shabby house, on a shabby street, in the new capital of Madrid, Luzia Cotado uses scraps of magic to get through her days of endless toil as a scullion. But when her scheming mistress discovers the lump of a servant cowering in the kitchen is actually hiding a talent for little miracles, she demands Luzia use those gifts to better the family's social position. What begins as simple amusement for the bored nobility takes a perilous turn when Luzia garners the notice of Antonio Pérez, the disgraced secretary to Spain's king. Still reeling from the defeat of his armada, the king is desperate for any advantage in the war against England's heretic queen—and Pérez will stop at nothing to regain the king's favor. Determined to seize this one chance to better her fortunes, Luzia plunges into a world of seers and alchemists, holy men and hucksters, where the line between magic, science, and fraud is never certain. But as her notoriety grows, so does the danger that her Jewish blood will doom her to the Inquisition's wrath. She will have to use every bit of her wit and will to survive—even if that means enlisting the help of Guillén Santangel, an embittered immortal familiar whose own secrets could prove deadly for them both.

Hell is empty and all the devils are here… Alex Stern made it to hell and back more than once, but this time she left the door open behind her. Demons are creeping through the streets of New Haven and the Yale campus, feeding on the souls of the living, terrifying the dead. Alex and her allies can hunt them, but it’s only a matter of time before the gates to the underworld open and they face a war they cannot win.

But for the first time in her life, she won’t have to face the fight alone. Dawes, Turner, Mercy, and even Tripp will have a role to play, none more so than Alex’s mentor Darlington, the golden boy who lived so long in her head, now back in the flesh and cursed with dangerous powers of his own. Hell itself is stalking the delegates of Lethe House, and they’re all about to learn that demons don’t play by human rules.
