Jar of Hearts Summary: The Full Story
SPOILERS: This section reveals all major plot points and the ending.
The story opens with the trial of Calvin James, the Sweetbay Strangler.
Georgina “Geo” Shaw, once Angela Wong’s best friend and Calvin’s high school girlfriend, testifies against him as part of a plea deal. Angela disappeared fourteen years earlier, and her remains have finally been discovered.
Geo has built a successful life as a vice president at Shipp Pharmaceuticals. She is engaged to the company’s CEO, Andrew Shipp. That life shatters when she admits to helping Calvin bury Angela’s body in the woods behind her childhood home.
Geo receives a five-year prison sentence. She enters Hazelwood Correctional Institute, nicknamed “Hellwood,” where she is immediately targeted by an inmate known as “The Mammoth.”
To survive, Geo forms an alliance with Ella Frank, a powerful drug lord serving life sentences. Geo uses her business skills to launder money and set up college funds for Ella’s children.
While Geo serves her time, Calvin escapes from prison after killing a guard and a counselor. Detective Kaiser Brody, the third member of Geo and Angela’s childhood trio, investigates a series of new murders.
Two bodies are found in the woods behind Geo’s childhood home: a dismembered woman and a strangled two-year-old boy named Henry Bowen.
The killer used a specific shade of Shipp Pharmaceuticals lipstick called “Cinnamon Heart” to draw a heart on the child’s chest with the words “SEE ME.”
Kaiser discovers that Henry’s biological father was Calvin James, and the dead woman was his biological mother, Claire Toliver. A second set of victims, Sasha Robinson and her four-year-old daughter Emily Rudd, are discovered shortly after.
Flashbacks reveal the truth of the night Angela died. At a high school party, Geo and Angela went back to Calvin’s apartment.
After a series of provocative dances and a brief alcohol-fueled encounter between the three, Geo passed out. She woke to find Calvin raping Angela.
When Angela threatened to go to the police, Calvin strangled her with his belt while Geo, paralyzed by shock and intoxication, did nothing.
Calvin then forced Geo to help dispose of the body. It is revealed that Geo herself took the saw and finished dismembering Angela when Calvin became too nauseated to continue.
Days later, Calvin raped Geo before disappearing, leaving her pregnant. Geo gave birth to a son, Dominic, whom she placed for adoption with Nori and Mark Kent.
She believed he was safe, but letters he sent her in prison reveal a traumatic childhood of abuse and foster care.
Upon her release, Geo returns to her childhood home, which is being targeted by vandals.
She finally meets Dominic, now eighteen, who bears a terrifying physical resemblance to Calvin. Geo realizes that Dominic is the killer, not Calvin.

Dominic murdered Calvin’s other children out of a sociopathic fury that they had “good mothers” while he was abandoned.
Dominic attempts to attack Geo, but Calvin, who has been secretly watching Geo since his escape, intervenes. Calvin admits he came back because the new murders “called him home.”
Confronted with the two monsters of her past, Geo shoots and kills both her son and Calvin.
The epilogue finds Geo a year later. She has found a semblance of peace and is in a relationship with Kaiser Brody.
She visits Rose Hill Cemetery, where Angela, her mother, and Dominic are all buried. Geo is pregnant with Kaiser’s child, viewing it as a second chance to be the mother she could not be before.
