A field researcher-in-training named Dr. Oli Morgan informs Quinn that a massive stone monolith has appeared in the forest behind UO Wyeleigh. Quinn is unfazed, allowing Morgan to realize that she can see the monolith only because she has started taking routine mnestic drugs. The drugs counter the monolith’s antimemetic clouding field.
Quinn leads Morgan to the monolith, which is catalogued in the Organization database under designation U-9429. After locating the entrance steps on one side of the stone, Quinn says something inaudible to U-4987, which is blocked out by the stone’s clouding field. Quinn and Morgan ascend the steps. Morgan observes that the stone is alien in origin, but is unlikely to have been moved to its present site, given its size, mass, and composition. She also observes the presence of engraved rectangles on every wall of the stone. Guessing at their meaning, Morgan references the long-term nuclear waste warning messages devised by Sandia National Laboratories.
Quinn and Morgan reach a plateau where an Organization research outpost is established. Morgan concludes that the stone is the memorial of a widespread antimemetic conflict. Quinn is impressed with Morgan’s deductive abilities, suggesting that she hired Morgan to solve problems that Quinn herself couldn’t. Quinn explains that despite the Division’s understaffing issues, their researchers have stumbled upon evidence of the culture that produced the monolith. They know that the culture was human, existed several millennia ago, and had reached a point of technological advancement that far surpassed contemporary humankind. The precise cause of their extinction is unknown, but it’s linked to an idea complex that their version of the Antimemetics Division failed to resist.
Morgan is shocked by the implication that millions died in this conflict, yet no one can remember it. Quinn emphasizes that there are “some things we have to remember” (78), suggesting that storing information is crucial to humanity’s survival. Research looks low-risk on the surface, but certain memetic crises can put the whole world at stake. The Organization’s primary objective is to research Unknown science until it can develop the means to address those crises. Given the conflict that produced the monolith, Quinn predicts that at least one more similar-scale conflict will occur in the near future.
Quinn says the idea complex that eradicated the older civilization is now contained, catalogued under designation U-9429-B, and can’t harm contemporary civilization because it isn’t designed to understand that idea. Morgan wonders what the idea looks like, which leads Quinn to believe that Morgan can perceive something she can’t. Morgan describes a large pillar composed of spiders, towering over the monolith. Quinn becomes worried, especially after Morgan sees the pillar (which has a rider) turning its attention to her. The rider is a young man bleeding from gunshot wounds. Quinn urges Morgan to learn his identity without giving away their identities. The rider takes control of Morgan’s body, preventing her from retreating on Quinn’s order. Quinn urges Morgan to break away, knocking her out when Morgan finds the effort too difficult. Morgan experiences cardiac arrest. Quinn tries to revive her, but ultimately flees.
As Quinn escapes the monolith, she reflects that the Unknown that killed the old civilization is back in full force. The only thing that can defeat it is a countermeme, which must be developed in an insulated laboratory like the one at UO Wyeleigh. Quinn encounters the rider whom Morgan saw, who tells her that he’s getting back at her for their encounter at the lake. Quinn doesn’t remember what he means. The rider emits millions of spiders that rush toward Quinn, but then Quinn steps out of U-9429’s clouding field and loses sight of the threat.
Quinn is at home when she hears an intruder enter through the front door. She pins the intruder down. The intruder identifies himself as her husband, Adam, and references “Sunshine,” their nickname for U-4987, to prove his identity. Quinn nevertheless has Adam detained to verify his claims.
Ives confirms that Adam is indeed who he claims to be: a concert violinist who met Quinn after being involved in an encounter with an Unknown designated U-8051. Ives wonders why Quinn can’t believe Adam’s claims, indicating that U-4987 likely consumed her memory of Adam to explain what happened. Quinn believes Ives only when he produces a Class Z mnestic autoinjector pen that Adam was carrying, proving that Quinn trusted him enough to carry such a lethal drug for emergencies. She reviews Adam’s file.
The novel flashes back to Adam’s encounter with U-8051, also known as the Digit Thief. Adam went to the hospital after scratching himself on a rusty nail during a concert. There, he noticed multiple people awaiting treatment for severed digits. The digits joined together into a large mass that spotted Adam looking at it. Adam then called emergency services to contain the mass.
The mass chased Adam through the hospital. UO Field Agent Marie Sheridan intercepted the mass and fought U-8051 back with a gun, though this failed to deter it. Just before it reached her and Adam, Sheridan located a riser cupboard for them to escape through. She then resolved to reach the roof to call for support.
Sheridan asked Adam about his work as a concert violinist since she enjoyed classical music. After calling for backup, she reassured Adam that he did well. Adam asked for clarity on their situation, so Sheridan explained the nature of U-8051 to him. Adam referenced the Illuminatus! Trilogy to signal his understanding, which Sheridan appreciated. Sheridan then explained the nature of her work to contain dangerous Unknowns. She contrasted her work to the series The X-Files, which she disliked. The conversation turned into a flirtation between them.
In the present, Quinn finishes reviewing Adam’s file. After several rounds of questioning, Adam asks to see his wife. They reunite after he’s placed in a containment unit. She admits her failure to remember him and her unwillingness to rebuild her relationship with him from scratch. When he tries to find out what Quinn can recall, she confesses that all her memories center on work. Adam reminds her of the care he extends to her every time she returns home and the trust he shows whenever she states that she can’t explain the nature of her work. Adam deduces that she’s working to resist a large-scale conflict. He reminds her of their common interests and the life they share. He expresses his faith that Quinn can remember him because they’ve been away from each other for extended periods before.
Quinn fixates on the detail Adam shared about the large-scale conflict. She realizes that she has large gaps in memory as a result of her participation in the war, which doesn’t affect Adam because he’s a nonparticipant. In addition, Adam reveals that he can see Sunshine because he’s immune to certain antimemetic effects. He theorizes that Sunshine erased Quinn’s memories of him so that it can prepare to kill him, which Quinn denies because it doesn’t fit Sunshine’s behavioral patterns. She suggests instead that Sunshine is trying to protect him, though she’s unsure why. She insists that they can’t be together, while Adam insists on keeping his marriage vow to protect her.
Quinn uses Sunshine to block Adam’s ability to perceive her. Adam cautions her that she’ll instinctively feel something missing from her life. Quinn promises that she’ll work to regain her memories after she wins the war. Adam wonders what she’ll do if she loses. Quinn considers using the autoinjector pen on Adam, but decides not to. She instructs her people to replace everyone’s memories so that no one can remember that she and Adam are married.
Nine months after the encounter with Gage, Quinn gives Lee the file on U-3125. The file has no information other than a protocol recommending that this Unknown be visited every 63 days. Though the lack of information makes Lee reluctant to help with the task, Quinn has him accompany her to the containment unit, which Ed Hix designed. She enters the containment unit, and Lee supervises from outside.
Inside the unit is a war room. Paperwork and scribbled notes cover the walls. A recording of Quinn plays from a laptop, informing her that U-3125 doesn’t inhabit the unit. Rather, the containment unit insulates Quinn from U-3125’s influence since it pervades every part of reality, manifesting in various forms that defy conventional reality. When someone understands the pattern behind U-3125’s manifestations, it identifies the beholder and kills them, along with anyone in mental proximity to them, to evade being known.
From this information, Quinn pieces together all the notes in the unit and understands the terrifying magnitude of U-3125. The video of Quinn displays a diagram of a hand with an opening in its center and suggests that the Division has already lost the war and that the present Division she works for is merely a remnant of survivors. The video of Quinn directs the present Quinn’s attention to a machine that Ed Hix designed, which will allow them to overturn U-3125’s dominion over reality. The only way to ensure the completion of the device is to build it with such discretion that no one can ever question the existence of any progress on the project. Quinn realizes that, over the last few months, she has been following through on this plan by preventing the Division from rediscovering U-3125.
The video of Quinn expresses discomfort and ends the recording once it starts distorting. The present Quinn wonders what made the Quinn on the video give up her recording, and who she was referring to when she mentioned a man named Adam. After reverse-engineering the containment unit’s construction, Quinn theorizes that a second insulated room contains Ed Hix’s device.
Quinn tries to figure out how to retain her memories of the device without eliciting U-3125’s attention. When she steps out of the unit’s airlock, a built-in purging system automatically erases her memories of the time she spent inside the unit. She tells Lee that she blacked out in the airlock and has retained memories of a plan, which Lee reminds her is impossible. Lee tries to examine something on Quinn’s neck, though the novel redacts the precise nature of this object. Quinn realizes that U-3125 has taken control of Lee in an attempt to kill her. She similarly resists its attempts to control her mind. Once she breaks away from Lee, Quinn flees from U-3125. An explosion breaks through the facility ceiling.
Part 2 veers away from the vignette structure of the previous section to continue developing the overarching conflict and the challenges that Quinn faces as she attempts to resolve it. The chief problem she faces is the antagonist’s ability to manipulate any knowledge of it to its advantage. Chapters 1 and 3 of Part 2 demonstrate this directly, as they depict U-3125 confronting Quinn as soon as she rediscovers its existence.
Quinn’s determination to win the current Antimemetic War defines her, as is evident in both her stated intention to defeat it and her long-term use of mnestic and amnestic drugs that ensure her continued participation in the conflict. The novel explores her self-sacrificing character trait by testing the limits of what she’s willing to lose to achieve her objective. This culminates in Part 2, Chapter 2, when Quinn realizes that her relationship with Adam is both an asset she needs to protect from U-3125’s knowledge and a liability that hinders her ability to participate in the war. Quinn clearly values her relationship with Adam. The flashback in the chapter deepens their relationship by establishing their common interests and views. When Adam makes his appeal to Quinn, he grounds his argument in the same general idea: They fit each other perfectly, which is the easiest proof for their relationship. He even argues, “We can be apart for two months while I’m on tour or you’re overseas and snap right back and pick up a conversation from the word we left off. We’re connected, Marie. We are of a mind” (111). This resonates with Quinn’s explanation for Lee’s success in Part 1, Chapter 2, in which she indicated that some knowledge is instinctive, living in the body rather than in the mind. This concept thematically drives Knowledge as a Form of Hope, as Adam appeals to Quinn’s implicit knowledge to restore their relationship.
Rather than convincing Quinn to work toward rebuilding their relationship, however, the arguments only strengthen Quinn’s resolve to detach herself from Adam. She worries that he may become collateral damage because she participates in the war. Though she doesn’t remember it, this already happened in Part 1, Chapter 3, when Quinn tried to extract intelligence from her former boss, Andrew Hilton. Hilton reappears in reverse-aged form as the rider controlling the spider pillar in Part 2, Chapter 1. Quinn’s failure to recognize him reflects both the severe effects of the reverse-aging process on his body and the impact of Quinn’s chemical attempts to alter her memory. If Adam can deduce the nature of the antimemetic war from its impact on Quinn, then he, too, remains perpetually at risk of being manipulated by U-3125. By erasing and replacing the memory of her relationship with Adam, Quinn spares him from the fate that Morgan and Lee experience at the end of Chapters 1 and 3 in Part 2. This introduces another major theme, The Human Cost of War.
Quinn is so devoted to the effort of the antimemetic war that Adam challenges her resolve to prioritize it over their relationship. When Quinn promises to remember Adam after she wins, Adam asks her what she’ll do if she loses. Part 2, Chapter 3 steers the conflict in this direction when Quinn rediscovers that this may already be the case. While insulated in the containment unit, Quinn realizes that U-3125’s ability to instantly kill anyone who can think of it is proof that it has already won the war. The implication of Quinn’s video message to herself is that she has applied various protocols to prevent the Division from discharging its function as a research unit because this would simultaneously guarantee that U-3125 would obliterate it. The containment unit itself thus represents hope in Quinn’s war efforts. Doubling as a war room, the unit’s insulative quality reminds her that some forces aren’t omnipotent, even if they’re omniscient. U-3125’s power can only go so far. By reminding herself of its limitations, Quinn recommits to discovering the device that was built to counteract it. This informs the remaining chapters in this part of the novel.
