The Swan's Daughter

On the Isle of Malys, Araminta, a veritas swan whose song compels truth, has spent six years brooding in Hush Manor, a cloud-borne dwelling in the Silent Lakes district. Years earlier, the wizard Prava courted her in disguise until she fell in love. When she confessed her feelings, a winged key necklace appeared in his hand, granting him control over her ability to shift between human and swan form. Prava keeps her compliant with daily tea infused with a drop of hope, telling her she will die without it.

Araminta hatches six daughters, each born with wings and a winged key necklace that Prava collects, planning to barter his daughters to distant rulers as spies whose truth-compelling songs will extract secrets for his quest for immortality. A seventh egg hatches late: Demelza, who resembles her father with russet hair and green eyes but possesses no wings and no necklace. Her key is locked deep in her heart and can only be summoned by love.

Prava excludes Demelza from her sisters' training, leaving her to study under the Manor's library wyvern, a dragon in rabbit form. Over 17 years, the six sisters conquer neighboring kingdoms and send back magical riches for Prava's immortality spell, which lacks only a final component: a sacrifice described in a damaged inscription. Demelza dedicates herself to deciphering the spell, hoping to prove her worth. Araminta, having glimpsed a fragment of Demelza's future, disguises her daughter's beauty with rags and ashes, keeping Demelza beneath Prava's notice.

When Demelza overhears Araminta urging Prava to "get rid of" her, Demelza is devastated. But Prava has just deciphered the spell's missing words: "a sacrifice of an unripened heart, born of beauty and beast." The sacrifice is Demelza's heart, born of Araminta and himself. When Demelza confronts her parents, Prava cheerfully informs her that all she must do is let him carve out her heart.

Araminta, forced into swan form, visits Demelza in secret. She gives Demelza an enchanted knife and reveals a royal invitation: King Eustis and Queen Yzara are hosting a tournament at Rathe Castle for maidens competing for the hand of Prince Arris. Rathe Castle is the one place where Prava cannot spy or enter, barred for past treasonous ambitions. Araminta disguises Demelza with mud from the Silent Lakes, since Prava cannot magically see within his own territory, and urges her to flee.

Prince Arris, the 18-year-old heir to the Isle's throne, carries an ancient curse. Centuries ago, Enzo the Fool extracted a boon from the Isle's witch queen: Only his male descendants, or whoever possessed their hand and heart in marriage, could rule. The betrayed witch cut out Enzo's heart, establishing a pattern in which brides murder heirs to seize the throne's power. Arris has survived three such engagements and proposed the tournament to find genuine love. His twin sister, Yvlle, a necromancer who commands shadows and wears an eye patch, has enchanted the castle grounds to detect armed contestants.

Demelza arrives bedraggled and mud-caked. She catches a contestant plotting to kill Arris, forces a confession with her truth song, and proposes a bargain. She will use her truth magic to identify genuine contestants, and in return, Arris will let her shelter within the castle. He agrees. Demelza shares a suite with Ursula, a bear-shifter, and Talvi, a girl made of ice who was spoken into life by her two mothers. Yvlle discovers Demelza's secret and helps craft a cover story.

The tournament proceeds through three trials. In the first, a test of talent, Demelza confesses she has none; Arris grants a one-time exception for her honesty. In the evenings, he climbs to her window with dishes he has cooked, and they exchange intelligence and conversation. Demelza covertly interrogates contestants, exposing the siren twins Thalassa and Pearl, who plan to devour Arris. When Lady Edmea, a pink-haired fashion designer, publicly questions Demelza's absence from the prince's side, Arris and Demelza stage a kiss to quell suspicion. Though planned, the kiss shakes them both, and Arris realizes too late he should have told her his passion was real.

In the second trial, a test of discernment, Queen Yzara presents a feast and asks each finalist to add one element for visiting homesick dignitaries. Going last, Demelza discovers a flaw everyone missed: The meal lacks salt. The field narrows to six finalists. Demelza saves Edmea from a poisoning attempt by Cordelia, another contestant, earning Edmea's friendship. In an optional exercise, each finalist distills her identity into a fragrance; when the vials are anonymously presented to Arris, only Demelza's moves him.

Before the third trial, paired magical stones open a portal between Demelza's room at Rathe Castle and her parents' sitting room in Hush Manor. Prava urges her home, claiming he has abandoned the sacrifice; Demelza refuses. The third trial tests power. Living darkness floods the contestants' residences, summoning each individually. While others attempt to overpower or contain the darkness, Demelza recognizes it as a vast longing that wants to become something. She names it: the shadow of branches on snow, the gleam in a horse's eye, the shade where dreams ripen. The darkness transforms willingly, condensing into a jewel of molten midnight in her palm. Demelza wins the tournament.

Cordelia attacks Demelza with a dagger, having deduced she is a veritas swan. Arris intervenes, and Demelza impulsively kisses him. At his request, she invokes her truth magic so he can speak freely: He confesses he is already halfway to loving her and would rather be scared with her than safe without her. If she comes to the ball that evening, he will have his answer. Demelza arrives at the last moment, and when they laugh together, light and feathers burst around them as she transforms into a swan for the first time. Her heart key manifests as a winged necklace on Arris's wrist, and he returns it without hesitation.

On the eve of the wedding, Queen Yzara argues that a veritas swan who stays alive only because her beloved lives has not truly chosen him. Prava appears through the portal and reveals that returning the necklace was hollow: Arris can summon it back by wanting to. He discloses that a veritas swan whose beloved dies does not necessarily die; only the dreaming part of her heart perishes. Prava pushes a glass knife through the portal, urging Demelza to cut out Arris's heart and be truly free.

The castle merges the walls between their rooms, allowing Arris to witness the exchange. They face each other: Demelza with the blade, Arris with the necklace, which has involuntarily appeared in his grip. Each holds the power to destroy the other. Arris proposes a different foundation: mutual trust, chosen freely and renewed daily despite uncertainty. Both say "I do," and the necklace and the knife fall from their hands.

In the epilogue, Demelza and Arris marry. Edmea designs the wedding gown, and Ursula constructs the banquet. Prava watches from the portal and weeps; later, he confesses to Araminta the full truth about freeing a veritas swan, and she finds a way to imprison him. Yvlle and Talvi sit close together over a book of poems, hinting at a story yet to come. Demelza and Arris sit hand in hand, "perfectly terrified of one another," choosing each other not with certainty but with hope.
