The Collective

Five years after her fifteen-year-old daughter Emily was raped and left to freeze to death in the woods behind Brayburn College by a student named Harris Blanchard, Camille Gardener remains consumed by grief and rage. Harris was acquitted at trial after defense witnesses claimed Emily left with an unidentified stranger, and a sympathetic Rolling Stone profile recast the Blanchards as victims. Camille, a website designer, now lives alone in a drafty house in Mount Shady, a Hudson Valley town, taking antianxiety medication and barely holding herself together.

The novel opens with Camille at a ceremony at the Brayburn Club in New York City, where Harris is receiving a humanitarian award. Having mixed vodka with her medication, she screams "Murderer!" and charges at him before being tackled by a security guard. She is arrested, and her closest friend, Luke Charlebois, a character actor who received Emily's donated heart in a transplant, picks her up. Outside the station, a silver-haired woman presses a black business card into Camille's hand reading "Niobe," the name of a queen from Greek mythology who lost all her children and was turned to stone by grief. "It's a group," the woman says. "For people like us."

Back home, Camille watches the viral video of her outburst, which has become a meme under hashtags like #PsychoMom. She dyes and cuts her hair, then sinks into deeper isolation. She joins Niobe, a private Facebook group of mothers who have lost children to unpunished killers, and tells her story for the first time since the trial. Fresh white roses appear on Emily's grave accompanied by a card reading "Ağlayan Kaya," the Turkish name for the Weeping Rock that Niobe became. An email with a dark web link leads Camille to a site by the same name: an anonymous chat room where grieving mothers voice revenge fantasies. Words like "forgive" and "moving on" are banned.

Camille immerses herself under the alias 0417, Emily's birthday. When she types "I want him dead. For real," the site's administrator, 0001, reveals the chat conceals something deeper: a collective of mothers who carry out coordinated, anonymous revenge killings, each member performing one small task within a larger operation. Camille swears on Emily's memory never to betray the group and submits Harris Blanchard's name. Her first assignment arrives via burner phone: Purchase a Buck 119 hunting knife from a store near Albany and mail it to a PO box in Burlington, Vermont. 0001 confirms her induction.

Assignments escalate: buying kitchen timers at a flea market, transporting a woman between states, and surveilling a plastic surgeon named Dr. Edward Duval. Camille's mental health improves; she sleeps better and works with renewed focus. Then she hears that Ashley Shawger, the man who sold her the knife, has died in a bomb explosion ruled a suicide. In a photo of the scene, she spots a kitchen timer identical to the ones she bought. The collective is not role-play. Shawger, she learns, shot and killed a young man named Nathan Langford in a hunting "accident" decades earlier and was never imprisoned. She visits Nathan's mother, Violet Langford, who confirms Shawger bullied her son and likely killed him deliberately.

The operations grow more dangerous. 0001 pairs Camille with a woman who introduces herself as Wendy Osterberg, a woman in her sixties whose transgender son, Tyler, was bullied and sexually assaulted by a classmate and later died by suicide. After creating an alibi at a bar, they switch cars with other collective members and receive a Mercedes with something heavy thudding in the trunk. Camille opens it against orders and finds Gary Kimball, a billionaire convicted of running a child sex ring who served only months in prison. Despite hesitation, Camille and Wendy push the car off a dock at a deserted summer camp. It sinks with Kimball inside.

Days later, Harris Blanchard is found frozen in the woods near Burlington, dead of hypothermia nearly five years to the day after Emily died. A young woman told police Harris attacked her with a knife after they left a bar; she escaped, leaving him in the snow. The knife is the Buck 119 Camille purchased. 0001 sends a screenshot of Camille's earlier words and adds: "Ask of the collective, and you shall receive." Camille does not feel the vindication she expected, finding herself pitying Harris's parents. At his sparsely attended funeral, a protester named Jen tells Camille that she and other women at Brayburn were also assaulted by Harris. "She was the first," Jen says of Emily.

Camille's doubts sharpen when 0001 assigns her to greet Dr. Duval outside a cemetery. Duval recognizes her, stops in the crosswalk, and says, "You're one of them." A truck driven by a collective member strikes and kills him. She learns that Duval's daughter died in a hit-and-run and his wife, Natalie, recently died by suicide. Visiting Duval's sister, Camille discovers he was bedridden with leukemia throughout childhood, making 0001's claim that he bullied a boy to death impossible. She concludes Natalie was a collective member who told her husband about the group, and the collective killed them both.

Camille confides in Wendy and persuades her to arrange contact with an FBI agent. She identifies the silver-haired woman as Penelope Chambers, who wrote a college play titled Ağlayan Kaya in 1973 and later lost her twin sons to a drunk driver, making Penelope the collective's likely founder. Camille suspects Violet Langford is 0001 because both Violet and the administrator reference losing multiple children and share distinctive language about "walking through fire." She tests this by having Wendy engage Violet in person while messaging 0001 online; the two are never active at the same time.

When Wendy fails to check in the next morning, Camille drives to her address and learns from Carl Osterberg that his wife, Wendy, died six months ago after apparently jumping from a bridge. The woman Camille trusted had stolen the real Wendy's identity and story.

Camille digs up a shotgun she buried at a spot called Unicorn River. Penelope appears behind her, and Luke's ringtone sounds from her phone: Luke has been lured to Camille's house by a fake email and drugged by the woman posing as Wendy. At gunpoint, Penelope marches Camille home. Inside, the imposter reveals herself as Dianne, the mother of Camille's late therapist, Joan Lowell, her only surviving child. Dianne accuses Camille of causing Joan's death: A two a.m. phone call, made after Joan tried to end their sessions, woke Joan and caused the fatal fall down her staircase. After seeing the viral video, Dianne recognized a kindred grief and decided to grant Camille justice for Emily before killing her. Penelope offers a choice: The collective kills Luke, stopping Emily's transplanted heart, and Camille goes free; or Camille dies and Luke lives. Camille is given a bottle of drugged orange juice and drinks it, watching Luke breathe. Dianne says, "Die like Joan," and shoves Camille down the staircase. In her final moments, Camille sees Emily, her mother, her ex-husband Matt, and Luke, wanting only to hear Luke's heartbeat one last time.

An epilogue set one month later reveals Camille's death was ruled an apparent suicide. Luke, devastated, now works as an organ donor spokesperson. He and his girlfriend, Nora, are expecting a baby, the news they had planned to share with Camille. At a hospital, Luke meets Billie Dorsey, whose son was killed in a drunk-driving accident. As he leaves, he glances back and sees Billie talking to a silver-haired woman who presses something into her hand. Luke feels a powerful sense of déjà vu but cannot place the woman. The cycle of recruitment begins again.
