Every Summer After

At thirteen, Persephone Fraser arrives at her family's new cottage in Barry's Bay feeling lonely and adrift after a fallout with her school friend Delilah Mason. Next door she meets brothers Charlie and Sam Florek. Charlie is instantly confident; Sam, her age, is shy, serious, and unexpectedly easy to be with. Percy and Sam quickly become inseparable. They swim, watch horror movies, trade jokes, and talk with a candor Percy has never found at school. Sam asks Percy to make him a friendship bracelet, opening a tradition that becomes symbolic of their bond. He also shares the grief of losing his father, and Percy finds in him someone who sees her without judgment. Sue Florek, the boys' warm, capable mother and owner of the Tavern, welcomes Percy into the family and turns the lake into a true home for her.

Over the next few years, the friendship deepens. Percy reconnects with Delilah during the school year, but every return to Barry's Bay sharpens how much Sam matters to her. Delilah's flirtation with the Florek brothers brings Percy's jealousy into focus, and a cruel game of truth or dare ends with Charlie impulsively giving Percy her first kiss instead of Sam. That only heightens the tension between Percy and Sam, who begin having intimate conversations about attraction, first experiences, and how much they notice about each other. Sam supports Percy's growing love of writing, helps with her stories, and becomes the person whose opinion matters most. By fifteen, he is training her to swim across the lake, worrying over her safety so intensely that Sue reveals he has been preparing in case he ever needs to save her. Percy completes the crossing, but even as other boys notice her, especially Mason Buckley, her feelings remain centered on Sam.

When Percy starts working at the Tavern, she and Sam move into an even more charged closeness. They share shifts, swim at dawn, and finally admit their desire during a stormy night when Percy is too frightened to stay alone and sleeps in Sam's bed. They kiss, and Sue later gives them a frank talk about respect, patience, and protection. Still, Sam asks them to wait rather than rush into a relationship they might damage. Percy is hurt, but their connection only grows stronger. The next summer, while Percy is still dating Mason in Toronto, Sam finally admits he has wanted her all along. Percy refuses to cheat on Mason, but the truth is now out in the open. Mason's possessive behavior, and Sam's deeper understanding of her, make the choice clear. Percy ends things with Mason, and before summer ends, she and Sam finally stop resisting and become a real couple.

Their senior year is intense and happy, but shadowed by the future. Percy drives to Barry's Bay constantly, and she and Sam build their life around the Tavern, their families, sex, and plans for university. Sam says he loves her, and Percy imagines a future that can survive distance. But at Sam's graduation party she learns he secretly applied for, and accepted, an early premed workshop that will take him away weeks sooner than expected. The secrecy wounds her more than the departure. Once Sam leaves, the first stretch of long distance goes badly. He feels overwhelmed and insecure in his new environment; Percy feels abandoned and tries to hold on tighter. Sam eventually asks for boundaries and less contact so they can both focus, but Percy hears that as rejection. During this period, Charlie becomes her main comfort. He trains with her, distracts her, and after a painful night in which Percy believes Sam is pulling away for good, she sleeps with Charlie. She regrets it immediately, has a panic attack, and buries the event in shame.

Back in Toronto, Percy learns her parents are selling the cottage. Sam later becomes warmer again and returns believing in their future. When he comes to help pack up, he lovingly reunites with Percy and then kneels with his grandmother's ring, asking her to marry him someday. Unable to confess that she slept with Charlie, Percy rejects the proposal and asks for a break, hiding the truth behind claims that they are too young and that she cannot trust the future. The breakup devastates Sam. Charlie eventually tells him what happened, confirming the betrayal Percy never admitted. In the aftermath, Percy unravels. Sam stops responding, turns to drinking and reckless behavior, and even drunkenly propositions Delilah, who tells Percy the truth. Instead of facing her own pain, Percy lashes out and destroys that friendship too. As an adult, Percy builds a polished life in Toronto, becomes a successful editor, and keeps all her relationships emotionally shallow. Therapy helps with the panic attacks that began after Sam, but she never truly moves on.

Twelve years later, Charlie calls to tell Percy that Sue has died after years of cancer treatment and asks her to come to the funeral. Percy returns to Barry's Bay terrified. She reunites with Sam at the closed Tavern and finds their old rhythm immediately intact beneath the years. Sam is now a cardiologist who returned home to help care for Sue and assist with the house and restaurant. They talk, drink, and fall easily into old games and private references, but the night is disrupted when Taylor, Sam's girlfriend, arrives. Even so, the next day Sam brings Percy back to the lake. They revisit the dock, the boat, and the challenge of swimming across the water. A near-kiss in the boat is stopped only because Percy remembers Taylor. Charlie, tense and protective, warns Percy not to be fooled, and Percy senses that the brothers are carrying older damage than she understood.

That night Sam shows Percy the preserved basement room where they spent their teenage years and reveals that for years he bought horror movies he could not bear to watch without her. He also tells her he has ended things with Taylor and wants Percy to know he is being honest. The next morning, before Sue's funeral, his grief breaks open: he admits he is terrified of dying young like his parents before he has really lived. Percy comforts him, and the closeness turns physical. At the funeral, Sam's eulogy about Sue's lasting love for his father devastates Percy, especially while Taylor still seems close to him. At the wake, Percy overhears Finn and Jordie warning Sam not to get involved with her again because of how badly she hurt him, and she has a panic attack. Later, after Chantal pushes her to stop hiding, Percy helps Julien Chen clean up. Sam tells her he never got over her, and they finally make love.

Afterward, Percy confesses the truth she has carried for twelve years: she slept with Charlie. Sam's first reaction is raw anger, but the deeper shock is his admission that he already knew. Charlie told him after the breakup, which means Sam was not only mourning a rejected proposal but living with the knowledge that Percy had betrayed him with his brother. Percy flees and collapses into another panic attack near her old cottage. The next morning Charlie gently tells her Sue knew the truth too and still wanted Percy there because Sam would need her. When Percy and Sam finally talk honestly on the dock, Sam explains his side: he withdrew at school because he was scared and ashamed, learned about Charlie after Percy ended things, and later numbed himself with drinking and sex. Percy admits she never stopped loving him and that her shame convinced her she did not deserve him. Sam rejects that logic, admits he tried and failed to forget her, and tells her he forgave her long ago. He ties his old friendship bracelet around her wrist, and they choose to begin again with honesty instead of silence.

In the epilogue, one year after Sue's death, Percy, Sam, and Charlie spread Sue's ashes on Kamaniskeg Lake at sunset. Percy and Sam are openly together and living in Toronto, and Charlie is close by. Percy has also apologized to Delilah and begun repairing that old wound. As the family and friends gather for the kind of memorial party Sue would have loved, Percy prepares to propose to Sam with a ring made from embroidery floss, turning their long history of love, grief, betrayal, and forgiveness into a deliberate future.
