A #1 New York Times Bestseller From the New York Times bestselling author of Where the Dark Stands Still comes an atmospheric romantasy based on Swan Lake, following Odile as her plan to restore magic to her enchanted kingdom gets disrupted by a murder mystery--forcing her to beg for help from the young woman whose identity she stole. Can two girls--one enchanted, one the enchantress--save their kingdom and each other? 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. With her father's help, Odile transforms Marie into a swan and takes her place at court. But when the king is brutally murdered and her own brother is accused, her plans are thrown into chaos. Desperate to free her brother, Odile is forced to team up with none other than elegant, infuriating Marie, the girl she has cursed...and the girl she can't seem to stop thinking about despite her best efforts. To make matters worse, there are whispers that the king's murder was not at the hands of man, but beast. Torn between loyalty to her father and her growing feelings for Marie, Odile becomes tangled in a web of treachery and deceit. To save her kingdom, she must find the true path to magic...and find the real killer before they--or it--strikes again.
