Tampa

Celeste Price is a 26-year-old woman with an exclusive sexual attraction to adolescent boys, a fixation she traces to her first sexual experience at age 14 with a boy named Evan Keller. She has married Ford, a 31-year-old police officer from a wealthy family, purely for financial security and social cover, finding him sexually repulsive because of his age. As the novel opens, Celeste is preparing for her first day as an eighth-grade English teacher at Jefferson Junior High in Tampa, Florida, a career she has pursued to gain proximity to young teenagers. The night before school starts, she drugs Ford's wine with crushed Ambien so she can masturbate undisturbed.

Celeste has strategically secured a portable extension classroom behind the school, a trailer with a locking door and a loud window air-conditioning unit that masks sound. On the first day, she scans her classes for a suitable target, rejecting boys who are too physically mature, too boisterous, or too confident. In third period, she notices Jack Patrick, a quiet, slim, blond 14-year-old whose shy demeanor she finds ideal. Meanwhile, Janet Feinlog, a curmudgeonly veteran world history teacher, watches Celeste with open suspicion, questioning why someone so young and attractive would choose to teach middle school.

Celeste begins a calculated grooming campaign. She assigns journal entries to learn Jack's preferences and keeps him after class for seemingly innocent interactions, such as comparing hand sizes and asking him to choose a lipstick shade. She stakes out Jack's house, using binoculars to watch him through his bedroom window. She evaluates and rejects another student, Trevor Bodin, recognizing his impulsive temperament as too risky.

At the fall open house, neither of Jack's parents attends, which Celeste interprets as a green light. She escalates, whispering intimate questions to Jack after class and initiating physical contact. On a Saturday night, she watches through binoculars as Jack masturbates at his bedroom window. The following Monday, she confesses to Jack that she saw him, tells him she cannot stop thinking about him, and asks to kiss him. He consents. She gives him a prepaid cell phone and arranges to pick him up that evening. They drive to an abandoned farm, where Celeste guides Jack through his first sexual experiences.

The affair settles into a routine. They meet at Jack's house after school, particularly on Wednesdays when his divorced father, Buck Patrick, attends evening classes. Jack grows emotionally attached, writing love poems and telling Celeste he loves her. Celeste reluctantly says "I love you" once but discourages such talk.

Complications multiply. At school, Assistant Principal Rosen proposes firing Janet and moving Celeste into the main building. Desperate to keep her isolated classroom, Celeste volunteers to mentor Janet instead, submitting falsified evaluation reports. At home, Ford pressures Celeste to have children to unlock income from his father's trust. She flatly refuses, and Ford punches a hole in the drywall.

When Buck comes home unexpectedly one Wednesday and finds Celeste at the house, she claims to be tutoring Jack. Buck is visibly attracted to Celeste and entirely unsuspicious. At Jack's suggestion, Celeste agrees to pretend-date Buck so she can visit freely, since Buck's previous girlfriends always had access to the home.

The arrangement fractures when Buck walks in silently one Sunday and finds Celeste and Jack at the kitchen table in a compromising state. To secure Buck's denial, Celeste improvises a joke about overeating, then leads Buck to the bedroom and has sex with him. Jack witnesses the encounter from the doorway and is furious, accusing Celeste of having enjoyed the sex with his father. To appease him, Celeste offers exclusive sexual acts and proposes they drug Buck with crushed Ambien, the same sedative she routinely uses on Ford. They dissolve the powder in Buck's wine at dinner, drag his unconscious body to bed, and have sex beside him. Celeste undresses Buck from the waist down and leaves a fabricated thank-you note on his nightstand.

In March, Buck catches them in Jack's bedroom. Celeste finds him in the hallway in the grip of a heart attack, unable to breathe or call for help. She deliberately watches him die without intervening, reasoning that his survival would leave her fate in his hands. After confirming he is dead, she takes Buck's cell phone and the house phone, tells Jack his father had a heart attack, and instructs him to wait at least 30 minutes before calling 911 and to never mention her presence.

Jack misses 10 days of school and is devastated. His mother arranges for him to move to Crystal Springs after the school year. Jack tells Celeste "We killed my dad." She firmly rejects this. Buck's vacant house, tied up in a family property dispute, remains their meeting place, though Jack's engagement grows increasingly rote.

During her second year of teaching, Celeste identifies Boyd Manning, a sexually precocious student who subtly signals mutual interest. Unlike Jack, Boyd initiates contact and proves eager for experimentation. Celeste gives him Jack's former prepaid phone and uses the vacant house for sessions with both boys, telling neither about the other.

In mid-October, Jack arrives at the house unannounced and discovers Celeste and Boyd together. He attacks Boyd, whose head strikes a nightstand corner, producing a deep gash. Jack accuses Celeste of cheating and of having let his father die not for their relationship but to protect herself. He then flees. Celeste chases him outside, having grabbed a kitchen knife. Mrs. Pachenko, a school parent Celeste encountered at the open house, finds Celeste standing naked under a streetlamp with bloody handprints on her body and a knife in her hand. Neighbors call the police, and Celeste is arrested.

Ford's family provides an attorney named Dennis in exchange for Celeste's public apology, a promise never to speak ill of Ford, and consent to a swift divorce. She is charged with six counts of lewd and lascivious battery against two minors, and the judge grants house arrest until trial. Jack does not reveal Celeste's role in Buck's death, feeling too implicated. Ford visits Celeste one final time during the trial, drunk, asking "Why?" and whether she ever loved him. She turns away and asks him to turn out the light.

At trial, Janet testifies as a character witness, declaring Celeste a good person. Boyd testifies enthusiastically, visibly proud. Jack, now nearly 16 and aged by grief and a stint in juvenile detention for attacking Boyd, testifies tearfully that the sex was consensual. He and Celeste share a final look across the courtroom, his eyes conveying a new understanding that no one is looking out for him. The DA offers a plea deal of four years' probation, which Celeste accepts.

A year later, Celeste moves to a small beach town, working for cash at a cabana bar and spending her earnings on anti-aging treatments. She prowls the beach near resort hotels, targeting vacationing teenage boys, giving them fake names, and disappearing before connections form. She acknowledges that aging will eventually force her to target more vulnerable boys but insists many years of predation remain. She still fantasizes about Jack and Boyd as they once were, but the knowledge that they are now nearly 18 disturbs her. To preserve her memories, she sometimes reimagines that both boys died the night of her arrest, so they remain forever young in her mind.
