Tisaanah wakes from a nightmare. She is aboard a ship carrying nearly 1000 former enslaved people to Ara. A dark entity called Reshaye inhabits her mind, whispering that something is coming. On deck, Tisaanah struggles under Reshaye’s influence, which seems to be telling her to jump into the water. Max, Tisaanah’s companion, finds her and pulls her back from the rail. They discuss her darkening veins as a result of Reshaye’s possession and his concerns about returning to Ara. He feels the powers have been “too quiet” and are plotting something. Tisaanah reflects on her previous deal with the Orders: exchanging the power to topple the Threllian Lords for becoming their weapon. She tells Max she would understand if he cannot face another war and he insists he will not let her fight alone.

As the ship approaches the Towers, Max views them with bitterness, seeing them as “monuments to broken promises” (14). At the docks, warships fill the harbor and soldiers in unfamiliar uniforms line the pier. A captain named Elias declares them traitors for their association with Zeryth, who has apparently betrayed the rightful king, Atrick Aviness. His soldiers attack. Just as the group is overwhelmed, Syrizen—specialized, blind guards—appear and teleport them to safety.

Tisaanah and Max battle back-to-back on the docks until the Syrizen teleport the group to safety. When they arrive before a white stone mansion, Max goes rigid and pale. Through Reshaye, Tisaanah is flooded with his memories: Dark-haired siblings, his parents’ embrace, and Reshaye’s rage culminating in their murders. Tisaanah realizes they are in Korvius, Max’s childhood home. Nura—a member of the Order and Max’s former lover—walks past and mutters that Zeryth Aldris wants to see them.

Aefe, a former princess of the Sidnee Fey’s House of Obsidian, is competing in a pit fight. She loses the fight, being distracted by thoughts of her past and how her father removed her title “Tierness” and exiled her due to “tainted blood.” Aefe’s commander Siobhan warns her that her constant infractions—marked by X tattoos on her forearm—will lead to expulsion from the Blades, an elite fighting unit. While patrolling near the Wall, Aefe and her companions discover dead and dying Fey from the House of Stone. A copper-haired man with a gut wound pleads for sanctuary. Against orders, Aefe hoists him onto her horse. He identifies the attackers as humans—shocking, since humans are considered far weaker than Fey—before whispering he is 13th in line for the crown and losing consciousness.

Zeryth Aldris sits at Max’s former family dining table wearing a crown. He announces Queen Sesri is dead and produces a decree naming the Arch Commandant as regent—making himself king. A map shows rebel strongholds held by Atrick Aviness, who has seized the Palace. Zeryth assigns Max and Tisaanah to conquer key rebel houses. When Max refuses, Zeryth reveals a spell binding his life to Tisaanah’s, so if he dies, she dies. Tisaanah warns Zeryth’s hunger for power will be his undoing. Zeryth defines power as “sitting here alone in a room with four people who want to kill [him]” and knowing he will survive (41).

Shaken by Zeryth’s revelation, Tisaanah follows Max to the garden. He spots Moth, a child recruit who enlisted while they were away, and berates him for joining until Tisaanah intervenes. Alone, Max despairs that children will be sent to fight. Tisaanah insists on fighting Zeryth’s war to eventually free those still enslaved in Threll. Max tells her “no war can be fought with clean hands” but he refuses to let her face it alone (48). They embrace, kissing passionately.

Aefe and Siobhan report the attack to her father, who is skeptical that humans are responsible. Assigned weapon cleaning as punishment, Aefe finds herself drawn to the infirmary, where she watches over the unconscious copper-haired man and falls asleep beside him.

Max secures Moth’s transfer to his own division, accepts the title of General Farlione, and confronts Nura about the coup. Unable to sleep, he slips into the main house and stops before a family portrait. Reshaye speaks through Tisaanah’s body. Max orders it to leave, calls it a mimic that can only destroy, and threatens to imprison it if it harms Tisaanah. Reshaye cryptically replies that something searches for it from beneath. It then observes that it and Max have always understood each other’s darkest shadows.

After a brief emotional goodbye, Tisaanah watches Max leave for war. Tisaanah senses Zeryth’s deep insecurity and realizes he chose Max to gain the respect that comes with Max’s family heritage. Before a portrait of young Max, Nura says he was less afraid then; Tisaanah disagrees, believing the man he has become has gained something, not lost it. She visits the Threllian refugee settlements, dismayed to find the people living in crumbling “slums,” though her friend Serel insists this life represents freedom. Alone that night, Tisaanah communicates with Reshaye, which says it wants proof it existed and an end to its liminal state. She promises to help in exchange for cooperation.

The man Aefe rescued introduces himself as Caduan Iero. Aefe’s father arrives and Caduan describes the attack, where thousands of human soldiers overwhelmed his people. Aefe argues for action and her father agrees to contact their rival house, the Titherie. Days later, a sparse coronation is held for the new King Caduan, now the surviving member of the House of Stone. The delegation from the Titherie House of Wayward Winds arrives at sunrise.

Riding toward Antedale, Max introduces his two captains: Essanie and Arith, both assigned to report his actions to Zeryth. When a young soldier named Phelyp Aleor declares his honor to serve under Max, Max feels sick knowing he may die under his command. When Moth reveals he enlisted wanting to be useful like Max and Sammerin were at his age, Max assigns him as his assistant far from combat, telling him that sometimes the best thing is to be “useless.”

Tisaanah dreams of Esmaris—her former mentor—teaching her that dead men are useless as they forget your name, while mutilated survivors remember to fear you forever. Nura wakes her for an attack on Korvius by Kazara’s army. Zeryth invokes the blood pact to bind Tisaanah to his command. During the battle, Tisaanah freezes when she sees a wounded young soldier who resembles Serel. Repurposing Esmaris’s lesson, she convinces Reshaye that living witnesses are more powerful than corpses, unleashes a terrifying display of crimson butterflies and blood-red wings to force the army’s retreat. She then collapses the cliffs to seal the pass, winning without the massacre Zeryth demanded.

Queen Shadya leads the House of Wayward Winds delegation, her white wings stark against red curls. Five hundred years of the houses’ rivalry fills the air. When Caduan initially fails to bow, tension spikes before he drops to his knees. Shadya’s generals propose a small elite scouting team—two from each house—to investigate the human threat, while a joint army trains in preparation. Aefe’s father shocks everyone by appointing her to represent Obsidian. Caduan insists on joining, refusing to wait for answers about who destroyed his people. Afterward, Aefe finds her father alone. He tells her she has potential she fails to use and she is not suited to be “Teirness,” or princess. She tells him she does not want the title, only to be his daughter. He shows rare emotion before telling her the mission is crucial and asking her to show him her potential.

Summoned to Zeryth’s office still bloodied from fighting, Tisaanah defends her decision to force the army into retreat rather than slaughtering them by saying “a mountain of corpses” (113) would make him another Sesri, a previous tyrannical ruler. Zeryth snaps that as “a no-name bastard” (114) he must force respect. Back in her room, the backlash from her use of magic hits Tisaanah violently and she collapses into surreal dreams of white rooms and pain, blending her memories with Reshaye’s.

Nura visits Tisaanah with medicine. Reshaye addresses Nura through Tisaanah’s body but Nura shows no fear, saying her own hatred is stronger. Reshaye mocks her for envying Tisaanah but Nura warns that something else is coming and that “the real fight has barely begun” (119).

Max receives a report of Tisaanah’s bloodless victory but worries about the magical toll on her, as her condition is unmentioned. He sends a brief letter asking her to tell him she is all right. His army arrives outside Antedale to find the city’s forces waiting. When his captains press for an immediate assault, Max refuses, arguing a swift slaughter would make Zeryth another Sesri. When a sharp letter from Zeryth arrives—confirming that the captains are spying on Max—Max sends a one-line reply assuring Zeryth that he knows what he’s doing.
