At the chaotic encampment, Meryn keeps Saela in a secure tent in the Bonded section with Venna guarding her. While passing through the triage section where wounded soldiers are being treated, Meryn spots Roddert, a Strategos from her training cohort, among the dead, making the losses brutally personal.

In the command tent, Siegrid ignores Meryn and praises Noemi for refusing to defect to Killian. After dismissing the officers, Siegrid reports that Siphons have overrun the original defensive perimeter, that a powerful Astreonan general is bringing reinforcements, and that a defeat seems imminent. The corruption in Bonded magic is worsening, and the power surge since Meryn’s coronation has become a hindrance because troops haven’t had the time to adapt.

Meryn proposes using foresight to forge a path ahead. In a vision, she sees several possible scenarios, and every thread ends with her allies’ deaths until one shows her shadebending driving the Siphons back. She announces that this as the only viable route. Siegrid refuses, citing Meryn’s lack of control, but relents when Meryn offers to go to the front alone. Siegrid orders Stark to accompany Meryn.

Before dawn, Meryn asks Saela to lend her their mother’s opal necklace to amplify her power. When Meryn puts it on, Saela is compelled to seek Killian, revealing that the necklace has been blocking his sire bond. Meryn forces the necklace back onto Saela, mentally alerts Venna to guard it, and then joins Stark and their wolves and rides for the battlefield.

Meryn and Stark ride toward the Siphon encampment at dawn, making themselves visible to their own soldiers to boost morale before entering enemy territory. Meryn uses rifting to conceal their approach, and they silently kill several sentries before charging into the Astreonan camp.

They fight through the scrambling Siphons to the camp’s center. Meryn reaches for her shadebending, but it won’t surface. Anassa urges her to stop suppressing her anger and act her own way instead of following Siegrid’s enforced calm. Meryn channels her rage, drawing on the fates of Saela, Izabel, and her mother; Anassa’s centuries of isolation; and Killian’s betrayal. Power opens inside her, and shadow floods the camp.

The power soon overwhelms her. As Meryn loses control, Stark calls to her mind, and a shadow-spun link forms between them, braiding their thoughts and emotions into one consciousness. Meryn gives Stark the excess power, and together, they slam every nearby Siphon to the ground, killing hundreds. The effort exhausts them both.

The surviving Siphons regroup and then inexplicably retreat. General Ruby Navarro approaches under a white flag, representing King Lucien Brightbane of Astreona. Ruby says that Lucien seeks a ceasefire so that Astreona and Nocturna can unite against their common enemy, Alistair Brightbane.

The next day, Meryn, Stark, and Siegrid travel to the ruined Grunfall manor for peace talks with the Astreonans. Ruby proposes a permanent ceasefire and formal alliance, arguing that Astreona’s true enemy has always been Alistair, who has used the Nocturnan throne to challenge his brother, King Lucien, for five centuries. Ruby’s condition for ceasefire is that Meryn meet Lucien in person. Stark immediately refuses. Ruby responds with veiled threats, warning that refusal will bring Astreonan forces into Nocturna to clear Weisenstat.

Meryn uses foresight to decide. Refusal produces burning fields and starving children; acceptance is murkier but far less catastrophic. Anassa reminds her that a leader can only make the best choice with present information. Meryn asks for time to consult her advisors, and Ruby grants a 24-hour deadline before hostilities resume. As a gesture of good will, Ruby unexpectedly brings forth Meryn’s father, Fredrich, who is supposed to be dead. Fredrich is alive and has been turned into a Siphon.

Meryn is stunned to see Fredrich until she remembers that there was never a body at her father’s funeral, only a severed finger sent home in a box. Her magic surges, and she sends everyone away before pressing a dagger to Fredrich’s chest and demanding proof that he’s really her father. Fredrich describes a detailed memory of taking Meryn hunting on her ninth nameday. Meryn realizes that the man standing before her is indeed her father, though she has long stopped thinking of him as a hero. Fredrich explains that he didn’t return because his battalion was ambushed and he was left for dead, until Ruby offered him transformation instead of death. He stayed away to protect his family and because he was unwilling to leave his sire, Ruby.

Meryn tells Fedrich that Nathalia was pregnant when he disappeared, that his absence destroyed her mental health, and that Nathalia is now dead. Fredrich is shocked to learn that he has another daughter and expresses regret, though Meryn finds it hollow. Fredrich begs her not to let her feelings about him affect the decision of an alliance with Lucien and claims that humans live peacefully with Siphons in Astreona. Anassa notes that Astreona could help Saela. Meryn releases Fredrich from her shadow restraints and dismisses him coldly. Once he leaves, her composure breaks. She finds Stark waiting and says she needs to hurt something; he leads her away.

Stark follows Meryn as she races away on Anassa, her grief and rage leaking through the mate bond as shadow tendrils curl around her body. Cratos warns Stark that Meryn and Anassa are close to losing control.

In a clearing, Meryn screams, and her shadow magic erupts, toppling trees. Anassa and Cratos run off to spend their own aggression. Stark realizes that Meryn doesn’t need calm steadiness; she needs matching force. He orders her to hit him to relieve her anger. He grabs her throat and threatens to spank her when she hesitates. Meryn’s shock turns to outrage, and she fires an impelling blast at Stark.

They trade magical blows and knife-fight at close range, neither holding back. Meryn eventually knocks Stark down and pins him. Stark admits that he doesn’t understand the mental connection they discovered while fighting the siphons, only that it’s separate from the wolves’ mate bond. When Meryn asks to try forging the connection again, Stark agrees. She lowers her mental walls, the connection reforms, and their mutual desire becomes visible to both. Stark gives in and kisses her.

Stark’s rough, urgent kiss shatters the last of Meryn’s anger and grief. She pulls back to close their mental link first, wanting to feel him without their emotions entangled. She asks about Noemi, and Stark says their relationship is sibling-like. Meryn asks Stark to take control, and he agrees while making clear that she holds the real power. They have a passionate sexual encounter in the forest, and afterward, he holds her in the quiet woods.

As they dress, Stark becomes contemplative and withdrawn, and an awkward distance settles between them. The decision about Astreona can no longer be delayed.

Back at Weisenstat, Meryn, Stark, Siegrid, and Kryptos Alpha Hannelore review the maps and agree that accepting the ceasefire is their only viable option after the Phylax defection weakened Nocturna. Siegrid insists that they walk into Astreona with a high-level hostage; Meryn names Ruby. Siegrid agrees and confirms that Stark will accompany Meryn while Siegrid directs the Daemos forces in his absence. Meryn insists that Saela, Venna, and Noemi come too. Siegrid agrees. Stark remains silent throughout.

Afterward, Stark stares at Meryn and then walks away without a word, leaving her hurt and irritated. That night, Meryn tells Saela that they’re going to Astreona and will meet their father; Saela becomes silent and withdrawn.

At the Grunfall ruins, the Siphon delegation arrives. Ruby introduces Elias as their guide into Astreona. Fredrich steps forward, and Saela recognizes him immediately, responding to his halting introduction with one quiet syllable before looking away. Ruby notes that Saela reads as a Siphon and asks who her sire is; Meryn deflects. Ruby says that King Lucien can help manage the sire bond and tells Meryn to mention the necklace to him. Ruby and Fredrich then share an ostentatious public display of affection that unsettles both Saela and Meryn. With Saela riding in front of Meryn on Anassa, Meryn’s party follows Elias into Astreona—a first for a ruler of Nocturna in five centuries.

The horses’ slow pace frustrates Meryn and Anassa as they cross scarred terrain and burned buildings—exactly what Nocturnans have been taught to expect of Astreona. Gradually, greenery appears, and the landscape transforms into a prosperous valley of farms and settlements. Meryn, Stark, Saela, and Noemi are stunned, but Venna sees only a barren wasteland—an illusion the Siphons project for Nocturnan spies (as a Kryptos, Venna is a spy). Attendant Hanlen demonstrates by casting a threatening illusion on Venna. As the Siphons laugh, Cratos attacks, ripping off Hanlen’s arm and eating it. A tense standoff follows until Fredrich calls for calm and Elias restores order. Meryn warns that their magic must remain dormant for the rest of the journey.

That evening at a military outpost, Elias says that he and Davide are going into town for supplies. Meryn insists on joining them, and Stark refuses to let her go without him. With only one spare mount, they must share a saddle, and the memory of their recent intimacy makes the ride intensely distracting.

Tormented by Meryn’s proximity, Stark tells himself that their intimacy was a mistake and that protecting her from Siegrid’s schemes requires him to maintain his distance. In the prosperous Siphon town, Davide explains that humans and Siphons coexist throughout Astreona, with humans able to sell blood voluntarily. Elias claims that drinking from children is illegal and that Astreonans rehome with Astreonan families that Nocturnan orphans found at the front. Meryn and Stark are enraged at the presumptuousness of the Astreonans in rehoming Nocturnan children but hide their anger. Davide adds that Siphon transformation is strictly regulated to protect population balance. Meryn and Stark begin to understand that generations of Nocturnan rulers spread misinformation about Astreona to sustain the war.

When Elias and Davide leave, Meryn pulls Stark into an alley, holds a dagger to his throat, and calls him a coward for staying away from her since their encounter in the forest. Stark disarms her, pins her to a wall, and says that he’s wrong for her, as he’s a “monster” who will drag her down and whom nobles will never accept at her side. Meryn tearfully refutes him, insisting that he doesn’t know his own worth and that two broken people can build something new. She re-establishes their mental link to prove their unique connection. Before the argument resolves, a woman screams. They find two Siphons collecting blood as payment for unpaid rent. Stark kills one; the other seizes Meryn and threatens to snap her neck. Elias arrives with a golden sun brooch—King Lucien’s symbol of authority—and forces the Siphon to stand down. He then explains that blood debt collection is legal and that the woman will now bear responsibility for the murder that Stark committed on her behalf.

Back at the stables, Meryn tells Stark that she understands feeling broken because she feels the same way. She gives him a deadline to decide whether he will pursue a relationship with her.
