Chapter 34 Summary: “Lilia”

Content Warning: This section of the guide includes discussion of illness, death, death by suicide, graphic violence, sexual violence, mental illness, gender discrimination, substance use, and sexual content.


Lilia researches her mother’s family on the island. Vanessa’s mother passed a few years prior, after which her home became abandoned. Lilia breaks into the property and finds a painting of a garden that Vanessa painted when Lilia was a child.


She realizes that when her grandmother died four years ago, Vanessa had gone on a short trip under the guise of finding a doctor to remove a benign tumor from Bee’s eye. Lilia wonders if Vanessa actually came home for the funeral and got infected with the Noctisoma during her trip.

Chapter 35 Summary: “Lilia”

During Devryck’s class, Lilia researches his father, frustrated at the lack of information about him online. Vanessa became pregnant and left the study before the six women died, yet Lilia wonders if Devryck’s father killed her. She considers how to get close to him to uncover information.


After class, Devryck apologizes to Lilia for his behavior at the library. She flirts with him, hoping that he’ll respond more amiably when she asks again about Andrea, who attacked Lippincott. She asks if Noctisoma have a latency phase that might explain a delayed onset of the infection, though she doesn’t mention her mother or the study. He says that’s impossible and nicknames her “Curious Moth.”


Later, Spencer asks about the nature of Devryck’s interest in Lilia. He also reveals that Mel dislikes him because they kissed when she was drunk, and she accused him of sexually assaulting her. Despite their animosity toward each other, they agree on disliking Devryck. Spencer says that Mel likes to dig up stories and that Lilia shouldn’t trust her.

Chapter 36 Summary: “Lilia”

Lilia is studying for final essays when Spencer’s seamstress arrives with an extravagant dress for Lilia to wear to the gala. Lilia is hesitant to wear it around Spencer, assuming that he wants to date her despite her assertion that she isn’t looking for a relationship.


Lilia reveals to the seamstress that Vanessa is her mother and asks about both her family and Andrea. Mel told her that Andrea’s real name was June. The seamstress says that June was a burnout, while Vanessa was an accomplished young woman whose disappearance shocked everyone. The seamstress feels sorry for Lilia.

Chapter 37 Summary: “Devryck”

Devryck checks on Barletta, whose symptoms have worsened. He’s covered in scratches, despite lacking a weapon, and accuses Devryck of harming him. Devryck dismisses this as a hallucination.


Later, Devryck ponders Barletta’s unusual behavior, which was less aggressive and more skittish. He gets a call from a fellow Rook, who offers information on Angelo but is unable to track him down. His real surname is DeLuca, but—unknown to Devryck and his informant—Angelo has used a different last name while he’s been friends with Conner. Because of the recent appearance of Angelo on the news in relation to the CEO’s murder, they assume that he’s been killed by now.


Lippincott texts Devryck to ask him to come to the gala that evening. Devryck agrees but checks on Barletta first. He finds Barletta dead, having mysteriously pried loose a piece of stone and gouged out his eyes. Devryck is confounded, as the parasite only seeks water to escape into and breed within; it never drives its host to death by suicide away from water.


Devryck quickly deposits the corpse into a tank of water, in which the Noctisoma begin to escape Barletta’s body. Devryck will leave him there throughout the evening until all the worms have escaped. He hopes that these worms and their toxin will create a more successful elixir for his ailment; otherwise, he’ll need to find another victim.

Chapter 38 Summary: “Lilia”

Lilia walks into the gala. She’s intimidated by the sight of expensive decorations and rich people and moves to leave, but she spots Devryck outside smoking. They lock eyes, intensely attracted to one another, but Spencer interrupts and brings her inside.


The gala exists to fund Devryck’s research and repopulate the moths used in their studies. Inside the room is a large tank containing moths. When Spencer leaves to fetch Lilia a drink, Devryck speaks to her, asking about the nature of her relationship with Spencer and assuring her that people in the gala are staring at her because she’s “worth staring at” (337).


Lilia joins Spencer and Provost Lippincott, who is more polite this time. Lilia tries to provoke him into admitting that he knows her mother, but he merely invites her to dine with them when dinner is served. Lilia is sat next to a creepy older man, while Gilchrist sits next to Lippincott, despite their animosity toward one another. Gilchrist clearly dislikes Lilia.


The older man begins speaking to Devryck, who sits two seats down from Spencer. They exchange barbs. Lippincott keeps receiving private messages from a waitress, and the older man begins interrogating Lilia about where she’s from. He gropes her under the table, which only Devryck notices and calls out.


The others are shocked at the accusation. Lippincott is furious, as the man is a wealthy donor, but Devryck threatens him if he touches Lilia again. Lilia means to go after Devryck when he storms off, but she suddenly becomes dizzy and disoriented. Spencer takes her out for fresh air, and she again notices the mysterious figure in a plague doctor mask.


Spencer chases after the figure. Alone, Lilia falls, too ill to move. Someone arrives and takes her away to a car, and she faints.

Chapter 39 Summary: “Lilia”

Lilia awakens in the cell under Emeric Tower, handcuffed to the bed. Devryck appears and says that he didn’t want to risk having an unconscious woman in his office or be seen taking her to her room, lest rumors spread, so he brought her there. He handcuffed her for her safety, as she was sleepwalking.


He says that she was drugged with berries in which Noctisoma-infected moths lay their eggs. The hallucinogenic berries made her ill, but he analyzed a trace of her vomit under a microscope and found no actual Noctisoma parasites.


He says that Spencer has been accused of drugging Mel with the berries and assaulting her, but this wasn’t proven. Devryck is concerned because university cameras caught him carrying Lilia to his car, but he grows more concerned when she mentions that she’s been spied on by the plague doctor figure.


Worried that the footage and Lilia’s drugging will have him arrested, he asks her to vouch for him; she says that she will only if he makes her his paid assistant. They argue, but he ultimately agrees, threatening that she’ll regret it if she breaks any of his rules.

Chapter 40 Summary: “Devryck”

Devryck is frustrated with Lilia. He lied to her about the plague doctor figure, saying that she may have hallucinated it, but he knows it’s a Rook. He wonders if Spencer, as a newly initiated member, is messing with her, but this doesn’t explain the night of the gala.


He visits Lippincott, who’s still upset with him for insulting the rich donor. Devryck asks if Spencer is spying on Lilia, but Spencer has accused Devryck of wearing the garb and punching him in the face after the gala, with a black eye to prove it. Lippincott also brings up the footage of Devryck bringing Lilia to his car and tells him not to cause more scandals.


Devryck is furious but agrees not to let Lilia mess up their plans. He understands that there was tension between his father and Lippincott and doesn’t want to invite Lippincott’s ire.

Chapter 41 Summary: “Lilia”

Lilia meets with Dean Langmore to explain her story: She saw a plague doctor figure, Spencer ran off, and Devryck found her and brought her to the car. However, she lies and says that she threw up in his car, ran off, and stayed in the chapel, where there are no cameras.


When Langmore questions her claims, she accuses Spencer of drugging her drink with the berries. However, Lippincott manages her scholarship, so in the interest of avoiding a scandal, she agrees to drop charges against Spencer as long as she and Devryck aren’t investigated. She urges Langmore to investigate the plague doctor figure.

Chapter 42 Summary: “Lilia”

Lilia visits Devryck’s private lab in the basement of Emeric Tower. There are rooms where corpses are transported, stored, and cremated, as well as a lab and office, where she finds Devryck’s pet cat.


They begin their work, and Devryck explains the Noctisoma toxin’s capacity to alleviate autoimmune diseases. Lilia asks many questions and is met with annoyance. Eventually, she’s dismissed, and he walks her to the bus stop for her safety. On the way, they banter playfully.


Suddenly, Devryck suffers a seizure. She wants to call for help, but he manages to tell her no. When he recovers, he admits to his disease and why he’s studying Noctisoma. The cure that he’s been developing isn’t safe enough to allow him to publicize his research. She attempts to comfort him, but she realizes that he hates being touched.

Chapter 43 Summary: “Lilia”

Lilia tries to fall asleep. Her arm aches from where Devryck tightly grabbed her amid his seizure, but the sensation stimulates her into fantasizing about him sexually. She masturbates and then considers her long-standing sexual fascination with older men.


She has a night terror about her mother, and she finds that pressing on the bruise that Devryck’s grasp left helps distract her from the panic.

Chapter 44 Summary: “Lilia”

Lilia shows up to her next shift wearing the lipstick she wore to the gala, which she believes Devryck liked. He notices. She says that they should name the moths they study, and her naming spurs discussion of book characters and romance novels.


She performs various chores for the lab, and he again walks her to her bus stop. She teases him about female students being attracted to him. He says that under different circumstances, he would’ve pursued Lilia, and she says that she would’ve let him.

Chapters 34-44 Analysis

Devryck and Lilia’s relationship develops in earnest from this section onward. In her quest to learn more about Vanessa and June, Lilia seeks out a way to get on Devryck’s good side, including flirting with him. Thus far, pursuing her ambitions and discovering what happened to her mother have been her primary goals. While her actions suit that to a degree, she struggles to know when her actions are serving those goals and when they’re giving over to her impulses. This internal tension reflects Lilia’s increasing need to choose personal desire after years of self-sacrifice. Her decision to pursue Devryck is not just reactive but also rooted in a longing for autonomy and connection, especially after a lifetime spent caring for others. She and Devryck both understand the dangers of Forbidden Romance and Its Consequences, but they find the draw between them growing stronger. This becomes apparent during the gala, where Devryck is stunned by Lilia’s beauty. Beyond that, he protects her when she’s sexually assaulted by a donor. This moment of public defense acts as a turning point: Devryck prioritizes her safety over his own reputation and research funding, signaling a shift in his moral alignment. Their romantic connection begins to emerge as a catalyst for change, challenging their self-imposed isolation and forcing them to re-evaluate their previous convictions—Devryck’s detachment and Lilia’s restraint.


The donor’s harassment of Lilia also acts as an example of How Harmful Power Structures Shape Scientific Research. It becomes clear through Lilia’s investigation into the Crixson Project and the history of Dracadia that a consistent disregard for the health and safety of women and other marginalized people is present in their research. Scientists from the 1700s experimented on disadvantaged women, while Warren Bramwell’s study resulted in the death of women whose suffering was covered up instead of acknowledged. Though Devryck has an earnest aim in his work, others like Lippincott are only involved for the potential financial gain that could come when the findings reach the pharmaceutical market. Because of this, Lippincott is apathetic toward Lilia and the mistreatment she endures. This inherently skews the research and the purposes for which it is used; it also makes clear how precarious Lilia’s safety is at Dracadia. The power that Lippincott holds over Lilia’s scholarship and the way that Gilchrist and Spencer use their institutional positions to evade consequence reinforce how Dracadia protects its insiders at the expense of young women like Lilia—until they learn to weaponize the system in turn.


Still, Devryck’s affection for and defense of her encourages Lilia to have faith in herself. When she awakens from being drugged to find herself locked in Devryck’s lab, she blackmails him to ensure that she can get what she wants. Her coworker Jayda often tells her to “be audacious,” but it takes time for her to feel confident enough to do so. When she succeeds in coercing Devryck to accept her terms, she thinks, “I didn’t even know who was talking at that point. Maybe I had been infected and the parasite was steering the ship, because no way in hell was Lilia Vespertine that bold” (357). This demonstrates how she is overcoming the fear and insecurity developed throughout her life and gaining a sense of power in her surroundings. It also shows how capable she is when she receives care and support from others. Though she is actively trying to blackmail Devryck, she feels safer due to his protection of her. As the story progresses, his increasing support will enable her to prioritize her safety and needs. Notably, Lilia’s boldness is coded as infection—again tying her identity to the central metaphor of the parasite and the moth. Just as the infected moths become both more vivid and more erratic, Lilia’s own transformation is rooted in attraction, compulsion, and rebellion against containment.


The Impact of Past Trauma on Present Actions remains vital to both characters. Devryck’s seizure in front of Lilia triggers a profound vulnerability rooted in his childhood, and yet, unlike past encounters, he doesn’t shut her out entirely. Instead, he confesses the truth about his condition and why he studies the parasite. His efforts to develop a cure are deeply personal, not just scientific. Similarly, Lilia’s sexual attraction to Devryck is entangled with earlier pain; her post-seizure bruise becomes both a physical reminder and a coping mechanism. She presses on it during a nightmare, using the ache to ground herself. This speaks to a complicated relationship with pain and control—one forged through the loss of her mother and the instability of her home life. Trauma has sharpened her instincts for survival, even as it has blurred the line between comfort and danger.


Throughout these chapters, the recurring plague doctor imagery and the reappearance of the “Curious Moth” nickname underscore how visual and metaphorical motifs shape the narrative. Lilia’s symbolic role as a moth—drawn toward dangerous light—is heightened by her desire to uncover truths that could destroy her sense of self. Her continued sightings of masked figures also reinforce the motif of disguise and the ways that institutional histories are hidden behind elaborate facades. Just as the original moths were altered by infection, Lilia is in the process of transformation—physically safe for now but emotionally changed by every interaction with Devryck and each revelation she uncovers.
