"A tapestry of mysteries, myths, and machinations, all held together by a shimmering thread of love between women." —Samantha Shannon, #1 Sunday Times bestselling author of The Priory of the Orange Tree

This stunning Greek mythology–inspired sapphic fantasy blends the story of Eros and Psyche with legends of the enthralling, vampiric empousa—from the New York Times bestselling author of Lies We Sing to the Sea!

Desire binds them. Hunger compels them. Love will set them free. . . .

On the island of Zakynthos, nothing is more powerful than Desire—love itself, bottled and sold to the highest bidder by Leandros, a power-hungry descendant of the god Eros.

Eirene and her beloved twin sister, Phoebe, have always managed to escape Desire’s thrall—until Leandros’s wife dies mysteriously and he sets his sights on Phoebe. Determined to keep her sister safe, Eirene strikes a bargain with Leandros: If she can complete the four elaborate tasks he sets her, he will find another bride. But it soon becomes clear that the tasks are part of something bigger; something related to Desire and Lamia, the strange, neglected daughter Leandros keeps locked away.

Lamia knows her father hides her for her own protection, though as she and Eirene grow closer, she finds herself longing for the outside world. But the price of freedom is high, and with something deadly—something hungry—stalking the night, that price must be paid in blood. . . .
