Part 2: “The Surface”

Part 2, Chapter 18 Summary

Imogen discovers the Mage Seer is a Siren; Theo states that if a Mage Seer has any Gods’ power, they can amplify it with magic spell work. While there is no cost for Gods’ power, which is natural and can be used with limits, there is a steep cost for additional or unnatural magic. Imogen attempts to enter the hut alone to spare Theo the additional trauma, but he pounds against the door in protest. Upon seeing the Mage Seer, Rohana, who is gaunt, jaundiced, and monstrous, Imogen allows him inside. They offer their blood and are given a vial of black liquid to drink, which intoxicates them. Theo is knocked unconscious so Rohana can exact her payment—a piece of flesh and a piece of hair pulled out at the root. Imogen pays with her own flesh and hair instead.


Rohana gives Imogen a prophecy foretelling a crown ripped from the head, a bond cut from the blood, a queen drained of her divinity, and a king “wrecked and ravaged beneath her wing” (212). The contents of the prophecy will bring death and destruction to the kingdoms. Imogen assumes she is the queen drained of power, Theo the king ruined because of her, and that together they will bring devastation.

Part 2, Chapter 19 Summary

Rohana gives Imogen only one draught. She can sever the bond between Theo and Imogen, but Eusia’s bond will remain, as it was formed by taking a Siren bond and mixing it with magic. The blood rituals Imogen performed throughout her childhood are the likely cause of the bond, and only the one who performed the spell (Imogen) can break it. However, she must figure out how.


Rohana suggests Imogen return home. Thinking of her home in Seraf, Imogen remembers the Siren wing that hangs in the throne room. She realizes that the king in the prophecy is not Theo, but King Nemea, and the wing is Ligea’s. This leads to her discovery that Nemea is her biological father, and “what they have made” is Imogen herself (212).


Rohana gives Imogen parting advice: keep her bond with Theo and the additional power it offers so that she may survive her confrontation with Eusia. They are better together. She urges Imogen to take everything she wants because she will someday become like Rohana. Imogen drags Theo from the hut and to the home of Hector and Antonia, who nursed him back to health once before.

Part 2, Chapter 20 Summary

Imogen briefly informs the couple of her bond with Theo and their journey to see the Mage for a prophecy. They are given a room. Eventually, Theo wakes while Imogen is in the bath. When she exits, he sees the wound from where she gave her flesh to Rohana. Theo calls her over and holds her as he asks what he missed. Imogen informs him that she secured the draught for severing their bond and that only she can sever her own bond with Eusia. Imogen then tells him the first half of prophecy and about Nemea being her father but omits the fact that she will bring destruction.


Theo correctly assumes Imogen plans to take revenge on Nemea for everything but reminds her that her responsibilities are bigger than that. Imogen and Theo become intimate, during which Theo asks Imogen what she wants. She claims to want a home where she’s safe and feels less alone. Theo suggests Imogen throw the draught in the fire. He doesn’t want to unbind, because severing her bond from Eusia is too dangerous without his added power. Imogen reminds him of his duty to his people, which he claims this also adheres to.

Part 2, Chapter 21 Summary

Hector informs Theo of an attack King Nemea made on Ammos—one hour up the coast—two nights prior. Theo shutters the windows and locks the doors to the home, explaining to Hector and Antonia that Nemea is searching for Imogen. She is not only his wife and the queen of Varya now, but also a Siren and the daughter of Nemea and Ligea. That night, Imogen still hasn’t decided what to do with the severance draught. Theo tells her to take it if she believes that the bond is all he feels for her. Imogen knows things will end poorly between them because of the prophecy but also knows Theo has come to love her.


The next morning, Theo and Imogen begin their return journey. Imogen asks Theo about Rohana. He informs her that Rohana is 278 years into her 400-year tenure as Mage Seer. He doesn’t know where she learned magic but doesn’t believe she’s old enough to have been taught by the First Mage, who was executed for the way she used magic back when the Great Gods were new.


When Imogen explains what Rohana said about her bond with Eusia involving spell magic Imogen herself must have cast, Theo tells her spell magic makes the wielder sick. Imogen never experienced this during the rituals King Nemea forced her to participate in. Theo reveals there are books about magic back at the palace, but they are guarded by a hermitess who won’t allow even him access.

Part 2, Chapter 22 Summary

Theo and Imogen cross paths with a retinue of guards led by Commander Lachlan. He informs them of attacks on Ammos and Notos and expresses disapproval that their bond has not yet been severed. When Imogen tells him how the bond provides the additional strength she’ll need to survive killing Eusia and severing their bond, Lachlan is apathetic, claiming it is not Theo’s responsibility. Lachlan insults Theo’s ability to keep his duty separate from his love life, provoking a fight that Imogen must break up.


Their entourage is attacked by mercenaries hired by Nemea, including the men Theo and Imogen met at the caretaker’s cottage days prior. Imogen lashes out with her power against the mercenaries but snares Lachlan too, who nearly dies alongside them until Theo stops her. Lachlan’s men dispatch their enemies while Lachlan recovers. The near-deadly mistake convinces Imogen she must sever her bond to Theo if she wishes to keep him safe.


They travel for two days and arrive back at the palace during an engagement feast Empress Nivala has thrown for Princess Halla. Imogen informs Lachlan to retrieve Agatha, as she plans to take the severance draught that night while Theo is preoccupied. Before she leaves the celebration, Imogen is approached by the Nivala, who tells Imogen a story about her surname, Nel.


Twenty-five years ago, the Nivala held a remembrance for her late husband, which many rulers attended, including King Nemea and Queen Ligea. The Nels were a rich and powerful Obelian family who hosted a lavish dinner at their home. Their guests went for a walk in the gardens, but when they returned, the entire Nel family had been murdered. They were slashed open from throat to waist, and their jewels were taken off their corpses, including a ring that looked exactly like Imogen’s engagement ring.

Part 2, Chapter 23 Summary

Imogen leaves the celebration, suspecting Nivala knows who and what she is. Agatha meets Imogen in her chambers, where Imogen admits she loves Theo. Before Imogen can take the draught, Theo arrives and realizes what she meant to do. After Agatha is dismissed, Theo admits his feelings for Imogen, which go far beyond duty or the bond. They become sexually intimate, and Imogen decides not to take the draught.


Later that night, a man leaves books on magic at the door. The hermitess agreed to lend them to Theo for two days after a compelling note he wrote her about taking a wife and honoring his duty to aid, protect, and upkeep the realm.

Part 2, Chapter 24 Summary

Imogen combs the books for information. One teaches her about the First Mage, who began her spell work to overshadow her infinitely more powerful sister, the Great Goddess Ligea. The First Mage began mixing her own Siren blood with blood, sacrifices, and well-worded prayers until she created a new form of magic—though its cost was immense. The First Mage’s first spell was benevolent. She provided a prophecy for a pregnant woman, informing her that the child, Rohana, would be a great seer who would advise and protect the archipelago. Over time, the First Mage began to weaken. Desperate to replenish what her magic took, she went to Rohana’s home and emerged two days later much stronger than before. Rohana’s mother was never seen again.


A page depicting lineages of the Gods shows Ligea and her younger sister, Eusia. Imogen wakes Theo who tells her the First Mage was disemboweled and thrown in the sea off the coast of the Siren’s home island of Anthemoessa, which has long since been uninhabited due to blight. Imogen tells Theo that Eusia is the First Mage. When he asks how to kill something that’s already dead, Imogen answers: magic. Theo warns Imogen against it, as magic will require a steep cost from her, but Imogen sees no other way.


Imogen and Theo have sex, which is interrupted by the arrival of Lachlan and Agatha. When Lachlan becomes angry that Imogen did not follow through in severing their bond, Agatha scolds him for pressuring them to do what was done to them. Guilty, Imogen reveals the final part of the prophecy foretelling that Imogen will decimate the order of all things. Theo still doesn’t agree to sever the bond, even after hearing the prophecy.

Part 2, Chapter 25 Summary

Imogen pockets the severance draught vial as the court prepares for the traditional Obelian pre-marriage ritual. Everyone gathers on the beach where Princess Halla waits. Agatha apologizes to Imogen for Lachlan’s behavior. Imogen advises Agatha to empathize with the pressure Lachlan is under and rebuild their former relationship. Princess Halla pulls Imogen aside for a conversation in which she tells her of the duty she must uphold to her kingdom. Nivala has tasked her with giving her mother an heir. She is suspicious of the relationship Imogen has with Theo and asks her not to intervene, which Imogen agrees to.


Princess Halla begins the ritual, pulling Theo ankle deep into the sea with her. She asks for a happy marriage, many children, and a strong military fleet. She then cuts her palm and offers her blood to the water, chanting the same prayer that King Nemea would have his court repeat for Eusia. Imogen disrupts the ritual when she realizes who Halla worships. Halla reveals that Eusia performed a miracle for her family, granting Nivala a child (Halla) in exchange for the life of her husband. Imogen realizes that Nivala must have taught King Nemea how to worship Eusia all those years ago at the remembrance she held for her husband, which is why the Nel family was sacrificed shortly after.


Halla learns that Imogen is blood bound to Theo and is therefore his wife by law. She demands they sever the bond or face the wrath of Empress Nivala and her military. Imogen flees the beach and removes the draught from her pocket, drinking it on the return to her chambers.

Part 2, Chapters 18-25 Analysis

This section starts off with a hopeful tone. As Imogen and Theo draw nearer to the Mage Seer, Imogen thinks: “Anticipation and fear had turned my stomach sick, but I was mere days away from being free. Days away from being rid of all the virulent ties to my old life—of my bond to Eusia. Days away from starting a new life that was all my own” (203). Unfortunately, by the second chapter of this section, it becomes an exploration of the aftermath of the Mage Seer’s prophecy. Both Imogen and Theo begin to unravel beneath the weight of duty and its direct opposition to their self-indulgent desire to pursue their growing romance.


Cassidy uses the prophecy as a turning point that forces both characters to confront what they’ve been avoiding since the start of the book: the difference between what they owe the world and what they owe themselves. Imogen’s divine heritage and the revelation that she is the biological daughter of Ligea and King Nemea marks the end of her attempt to live an ordinary life free of responsibility. Her sense of identity fractures, and the “choice” between self and duty becomes an illusion. What began as a desperate attempt to claim freedom is now an inherited obligation. She can at least somewhat accept this due to her role in the tragedies that have occurred because of Eusia and the nekgya.


While Imogen has gradually accepted her duty to save the world from the growing threat of Eusia and her followers, Theo’s own commitment to duty is waning in comparison. His duty as king conflicts with his attachment to Imogen, and the clarity that once guided him starts to fade. By the time he and Imogen confess their feelings, their relationship has become the very entanglement they both vowed to resist. Unfortunately, this connection brings war to his kingdom when King Nemea attacks in search of his stolen daughter. Furthermore, the unknown complication surrounding Theo’s marriage to Imogen and engagement to Halla risks the wrath of the Empress, who is revealed to be a devoted follower of Eusia with massive military might.


The introduction of the Mage Seer is also the first fear-inspiring depiction of The Corrupting Pursuit of Power. Prior to this, Evander meets an untimely fate after attempting to force a blood bond from Imogen, and King Nemea’s cruelty and isolation are born of his own greed for power. However, the depiction of a Mage Seer as something truly monstrous fully showcases, both literally and symbolically, the corrupting nature of one’s pursuit of power. When Imogen first witnesses the grotesque physique of the Mage Seer in Varya, the Mage replies, “We always give something up for power, don’t we?” (207). Mages are Sirens who search for power beyond what they naturally inherited; while Imogen has no desire for additional power, it is what she needs to sever her bond to Eusia and kill the water deity for good. Seeing the cost such magic has exerted on the Mage Seer—and on Eusia herself, once Imogen learns Eusia was the First Mage—increases the already high stakes for the narrative.


The relationship between Imogen and Theo also reaches its most intimate point in these chapters, but Cassidy maintains the ambiguity of their connection by making Imogen doubt the validity of their feelings outside the bond. Even after Imogen and Theo admit to their feelings and have sex, Cassidy never releases the tension and uncertainty surrounding their relationship. Imogen shortly thereafter completes her perceived “duty” to the world by severing her bond with Theo, breaking their forced connection.


By the end of this section, Imogen no longer hides from who she is and what her duty entails, but she has also lost hope in ever having a life with the freedom to choose for herself. Meanwhile, Theo has learned what it means to want something for himself, but it costs him in terms of his leadership ability, bringing conflict to his homeland. Both characters have entirely switched sides on the spectrum between duty and self, and neither is at peace.
