The Stolen Heir

As a small child, Wren is found in a mortal alley and raised in foster care, beloved but visibly strange: cold-blue, strong, and unlike other children. At nine, Lady Nore, Lord Jarel, and the storm hag Bogdana invade her room and reveal that she is Suren, their faerie changeling daughter. When her human family recoils from her unveiled form and Jarel threatens to kill them if she refuses, Wren leaves to protect them. Two years later she briefly reappears traumatized and scarred before vanishing again.

Years later, Suren lives feral near her former human family, watching over them from a distance and sabotaging predatory faerie bargains. After she disrupts a glaistig’s deal, Bogdana tracks her to the house, forcing Suren to flee to draw danger away. Prince Oak of Elfhame and his knight Tiernan intervene, driving Bogdana off but capturing Suren. Oak explains that Lady Nore has reclaimed the Ice Needle Citadel, stolen Queen Mab’s imperishable bones, and is using their power to create stick-and-snow creatures and recruit cursed falcon soldiers. Because Suren was once Nore’s child-queen, Oak believes she can command Nore and help stop her.

Suren agrees to travel with Oak, Tiernan, and Hyacinthe, a former falcon-soldier bound by Grimsen’s bridle. Her choice is shaped by necessity: Nore and Bogdana are hunting her, and Oak offers both protection and a future boon. Flashbacks reveal why Suren both trusts and resents him. As children, Oak found her bound in the Court of Teeth’s camp, returned with Nightfell to free her, and hid her in Elfhame, but when the High Queen later banished Suren, he did not stop it. Later, as a young prince exhausted by assassination attempts, Oak sought refuge with Suren in the mortal woods; she sheltered him for one night but sent him home.

The quest first takes the group toward the Court of Moths to consult the Thistlewitch. Along the way Nore’s creatures ambush them, Oak is poisoned, and Hyacinthe warns Suren not to trust him. At Queen Annet’s court, hospitality becomes another trap: Hyacinthe is imprisoned, Suren is dressed for a revel, and Annet exposes Oak’s hidden motive. He does not merely want to stop Nore; he wants to rescue Madoc, the father who raised him, even though the High Court will not sanction the mission. Suren is furious at the concealment but agrees to continue for the moment, drawn by Oak’s loyalty and by her own complicated feelings for him.

Suren secretly frees Hyacinthe, along with a mortal girl named Gwen and a merrow, from Annet’s prison. She solves riddles to open the cells and breaks Hyacinthe’s wing-curse, after which he swears fealty to her. Her actions are discovered, and Annet tries to punish her through a contest. Oak chooses a duel and kills the ogre Noglan with ruthless precision, revealing the lethal nature of his training. Annet then poses a fatal riddle, but Suren answers with a paradox and wins release for herself and Jack of the Lakes, the kelpie who helped her.

The Thistlewitch reveals the deeper history of the stolen power: Queen Mab’s creation magic was tied to Mellith’s heart, and Mab’s bones still retain dangerous but limited force. Oak bargains a future favor for knowledge and learns that the heart must be kept from Nore. As the party travels north, Bogdana confronts Suren and claims she created her from snow, warning that Oak may trade her to Nore for Madoc and threatening Suren’s mortal family. Shaken, Suren attempts to flee alone with the bridle, but Titch, Oak’s owl-faced hob, retrieves it and her escape fails.

Oak clarifies that Nore offered to trade Madoc for Mellith’s heart, not for Suren, and reveals his plan to deceive Nore with a deer heart sealed in an enchanted reliquary. In Undry Market, they gather supplies and steal a magical cormorant boat after negotiations collapse. At sea, Oak returns the bridle to Suren and asks her to trust his intentions despite his deceptions. Mermaid Loana nearly drowns him while demanding a kiss, but grants concealment for their voyage. Hidden from Nore and Bogdana, the group reaches the frozen north.

Crossing toward the Ice Needle Citadel, Suren, Oak, Tiernan, and Titch are driven into the Stone Forest by Nore’s forces. Suren senses the ancient curse there and redirects it, splitting the earth and scattering attackers. Trolls then escort them to Speaker Gorga’s village, where Gorga poisons their drinks with blusher mushroom. Oak, resistant to it, drinks all three cups to spare the others. At dawn, Suren and Tiernan escape the barred lodging, steal a sled, and drag the poisoned Oak out of the forest until the Citadel comes into view.

Suren and Oak infiltrate the Citadel in disguise while Tiernan prepares a diversion. They witness Lady Nore animating more creations with blood and bone dust, then evade guards by staging a kiss before Oak kills the guards. Their search of Nore’s grotesque chamber fails, and a bed of frozen victims sounds an alarm. Captured, they are brought before Nore, King Hurclaw, and Bogdana. Oak bluffs that he has Mellith’s heart and negotiates a trade for Madoc. To prevent Suren from commanding her, Nore uses a petal spell and has Suren’s tongue cut out, then magically heals the wound so she remains silenced.

Hyacinthe secretly helps Suren in the dungeon by smuggling her a key. Beside Madoc’s cell, Suren overhears Oak refuse Madoc’s suggestion that she be killed. She escapes, finds a shard of Mab’s bone, and uses it to regrow her tongue, shattering nearby stick soldiers in the process. Recaptured and brought to Nore, Suren speaks commands that bind Nore to silence, nonviolence, and obedience. She and Oak then coordinate a new plan around the supposed exchange, using Nore, the reliquary, Madoc, and the Citadel forces as pieces in a larger trap.

At the exchange, Tiernan delivers the case said to hold Mellith’s heart. Hurclaw opens it and is struck by a poisoned dart, revealing Oak’s decoy. Battle erupts. When Suren is shot, memories surface: Bogdana placed Mellith’s heart in her chest. Suren realizes she is the unraveler, the being who can annihilate Mab’s creations. She collapses Nore’s stick army and, in fury, unmakes Lady Nore herself. She then frees Bogdana, has Hyacinthe deliver Oak’s antidote to Hurclaw, and secures the troll king’s allegiance by promising to end the troll curse. Rather than release Oak, Suren bridles him and keeps him as hostage, sending Tiernan and Madoc away with word that she has taken the Citadel for Elfhame.

Back inside the Citadel, Bogdana urges Suren to petition the High Court for recognition and found a new court, while concealing Oak’s captivity. Suren rejects being managed, frees the cursed falcon soldiers, and is hailed as queen. Yet her triumph feels hollow. When she visits Oak in his iron cage, he pleads to explain and atone, but Suren refuses to listen. Afraid of being swayed by him and hardened by all she has learned, she flees, leaving their bond unresolved and her new rule defined by power, fear, and wounded longing.
