Cruelty Free Book Summary (Spoilers Ahead)
Spoiler warning: the following section recounts the plot in full, including the ending.
In March 2014, twenty-nine-year-old Lila Devlin and her Marvel-actor husband Aidan Reynolds wake to find their fourteen-month-old daughter, Josephine, gone from her nursery. The case becomes a national spectacle.
Tabloid editor Nico DeLuca, paparazzi photographer Tommy Olsen, and LAPD detectives John Carmichael and Nick Fox all feed the coverage. A botched stakeout lets the kidnapper escape with the ransom money.
Weeks later, a burned toddler’s body is found near Lake Gregory and identified as Josie. The public turns on Lila, casting her as neglectful or worse.
Lila and Aidan divorce. She leaves the country and spends a decade in India and Europe studying chemistry and meditation.
When she returns, Lila reconnects with her former publicist Cara Donaldson, who declines to work with her and refers her to Sylvie Lightly. Sylvie is a blacklisted PR manager who served jail time after driving her car into a nightclub crowd.
Sylvie becomes Lila’s co-founder and closest ally. She also proves willing to do anything Lila asks.
Lila arranges a meeting with Nico DeLuca to make peace. When he invites her onto his podcast for an episode about “moms who don’t have children,” she cuts his throat with a box cutter.

Sylvie walks in, locks the door, and helps dismember the body. The two women conceal the remains and move forward with the business.
Lila then drives to Lake Arrowhead to find retired detective John Carmichael. Overcome with guilt about the ruined investigation, he hands her a note revealing the location of prime suspect Arthur Allen. She shoots him and stores his body in Sylvie’s garage.
In Slab City, Lila corners Arthur Allen in a yellow RV and slits his throat. He denies kidnapping Josie until his final breath, and his death brings her no relief.
Searching for a product differentiator, Sylvie suggests harvesting human collagen. The two women boil Allen’s bones into powder and build glob’s signature serum around it.
The formula goes viral on TikTok and national morning television. glob becomes a multimillion-dollar brand, and Lila becomes a celebrated founder.
They hire Maya, a USC chemistry student, as an assistant. Lila begins to think of Maya as a stand-in for the daughter she lost.
To sustain supply and settle old scores, Lila expands her list. She drowns podcast host Greer Houser in a Williamsburg bathtub, kills Cara Donaldson in her kitchen, and executes Tommy Olsen in a Van Nuys motel.
Meanwhile, Lila reconnects with Aidan, now remarried to a model named Sonnet and raising a seven-year-old daughter, Talia. During a private conversation, details of his story stop matching.
Lila works out the truth: Aidan came home drunk that night, dropped the baby, and staged a kidnapping to protect his career. He let her absorb a decade of public hatred.
Instead of killing him, Lila and Sylvie abduct Talia from her bedroom and bring her to Lila’s Encino house.
Maya arrives that night to stay over and finds Talia asleep on the sofa. Sylvie forces her into the basement at gunpoint, where Maya sees labeled jars of collagen powder, including one with her missing boyfriend Peter’s name.
Peter had been killed by Lila to keep Maya from moving to New York. In the wine cellar, Sylvie reveals her own secret: she was the original 2014 kidnapper, taking Josie to cover her husband’s medical bills and leaving the infant at a fire station when police closed in.
She hid Josie’s survival for ten years so Lila would stay with her. Lila shoots Sylvie in the stomach. Sylvie falls against the gas stove and the kitchen ignites.
The two women fight while the house burns. Sylvie stabs Lila in the heart; Lila slits Sylvie’s throat. Both die on the floor.
Before she dies, Lila opens the basement door. Maya breaks a high window with a golf club, boosts Talia out with a car alarm fob, and climbs through the burning living room.
Lila silently begs Maya for forgiveness. Maya turns away and escapes into the night.
In her final hallucination, Lila sees Josie as a teenager in a grocery store. Lila reaches for her, but her hands pass through the girl’s clothes. Josie cannot see or hear her, and as Lila dies she whispers, “I hope I haunt you.”
