London, 1848—For four hundred years, England has been under the control of an immortal fae queen who tricked her way onto the throne. To maintain an illusion of benevolence, Queen Mor grants each of her subjects one opportunity to bargain for their deepest desire. As Ivy Benton prepares to make her debut, she knows that not even a deal with the queen could fix what has gone wrong: Her family’s social standing is in shambles, her sister is a shadow of her former self, and Ivy’s marriage prospects are nonexistent.

Two hundred years ago, a slighted deity stole the magic from Auréal and vanished without a trace. But seventeen-year-old Odile has a plan. All her life, her father, a vengeful sorcerer, has raised her for one singular task: infiltrate the royal palace and steal the king’s crown, an artefact with enough power to restore magic. But to enter the palace, she must assume the identity of a noblewoman. She chooses Marie d’Odette: famed for her beauty, a rumored candidate for future queen…and Odile’s childhood-friend-turned-sworn-enemy.

It’s been centuries since a warm-season fairy in Pixie Hollow has crossed into the Winter Woods, and while most fear the legends of monsters lurking in the frozen lands, Clarion, can’t help being intrigued by Winter’s stoic beauty.

Inesa lives with her brother in a half-sunken town where they scrape by running a taxidermy shop. Unbeknownst to Inesa, their cruel and indolent mother has accrued an enormous debt—enough to qualify one of her children for Caerus’s livestreamed assassination spectacle: the Lamb’s Gauntlet. Melinoë is a Caerus assassin, trained to track and kill the sacrificial Lambs. The product of neural reconditioning and physiological alteration, she is a living weapon, known for her cold brutality and deadly beauty.

When the gold-dusted court invitation arrives at Suraya Saab’s forge, she believes it’s a joke. Nobles might seek her skills as a bladesmith—one of few who can imbue her work with precious jadu, the last source of magic in the realm—but she has no qualifications as a potential bride for the crown prince. Still, the invitation is the chance at adventure, and the means to finally visit the capital city her late mother loved. But what awaits her in Kaldari is nothing she could have imagined—and fraught with danger.
