Summer Sisters

Summer Sisters Plot Summary

Introduction

Victoria Leonard's world trembled the day Caitlin Somers approached her desk in sixth grade, transforming a quiet Santa Fe girl's life with a simple invitation to spend the summer on Martha's Vineyard. What began as an unlikely friendship between two girls from opposite worlds would span decades, weaving through love affairs, family secrets, and devastating betrayals. From their first summer as twelve-year-olds discovering the mysteries of adolescence to their final confrontation as adults grappling with the consequences of their choices, Victoria and Caitlin's bond defied easy categorization. Part sisters, part rivals, they shared everything from first kisses to deepest secrets, until the men they loved became the wedge that would forever alter their connection. This is the story of how summer friendships can burn bright enough to illuminate a lifetime, and how they can also destroy everything they once promised to protect.

Chapter 1: The Invitation: When Worlds Collide

Victoria Leonard sat in her worn bell-bottoms and juice-stained purple T-shirt, watching the golden girl who had transferred mid-year from Aspen. Caitlin Somers possessed everything Victoria lacked: platinum hair that caught sunlight like spun silk, confidence that radiated from every pore, and a family wealth that whispered rather than shouted its presence. While Victoria's father sold insurance and her mother worked for an eccentric Countess, struggling to support four children in a cramped Santa Fe house, Caitlin floated through life as if gravity barely applied. The classroom buzzed with the usual end-of-day chaos when Caitlin materialized beside Victoria's desk. Her approach felt choreographed, deliberate, like a predator selecting prey—though Victoria couldn't yet determine who was hunter and who was hunted. Caitlin's smile revealed perfect teeth as she delivered the invitation that would reshape Victoria's existence: "Want to come away with me this summer?" The words hung in the air like a spell. Victoria's mind reeled with impossibilities. Her family couldn't afford vacations, could barely manage rent and her brother Nathan's medical expenses for his muscular dystrophy. Yet something in Caitlin's eyes suggested this wasn't a casual invitation but a calculated selection. Victoria had been chosen, though for what purpose remained mysteriously unclear. The negotiations at home proved brutal. Victoria's mother Tawny viewed the Somers family with suspicion, recognizing the class divide that separated working people from trust-fund children. But Victoria's father Ed, a quiet man who rarely spoke above a whisper, surprised everyone by advocating for his eldest daughter. Perhaps he sensed this opportunity might be Victoria's only chance to glimpse a world beyond their financial constraints. When permission finally came, Victoria felt as if she'd won a lottery she hadn't known she'd entered.

Chapter 2: Dancing Queens: Summers of Discovery

The Vineyard house overwhelmed Victoria with its shabby elegance and casual disarray. Lamb Somers, Caitlin's father, embodied everything Victoria's own father wasn't—articulate, educated, comfortable with himself and money. He insisted she call him Lamb, treating her not as Caitlin's guest but as family, while his second wife Abby showered both girls with maternal attention Caitlin's biological mother Phoebe had never provided. In their shared bedroom overlooking Tashmoo Pond, Victoria and Caitlin invented their secret selves. They became Vixen and Cassandra, summer sisters bound by rituals only they understood. They counted Victoria's sixteen pubic hairs with scientific precision, painted their faces like ancient priestesses, and discovered what they called The Power—the electric sensation between their legs that promised mysteries yet to be revealed. The island itself became their playground and classroom. They learned about desire while watching Von, the golden-haired carousel operator who made both girls' hearts race. They experimented with stolen cigarettes behind the dunes and practiced kissing on each other to prepare for real boys. Victoria taught herself to swim at fourteen, driven by determination to match Caitlin's fearlessness in the water. Every experience felt heightened, saturated with the intensity that comes when childhood begins its slow dissolution into something more complex and dangerous. But beneath the summer magic lay undercurrents Victoria couldn't fully understand. Caitlin's relationship with wealth seemed simultaneously entitled and resentful. She craved attention yet pushed away anyone who tried to nurture her. Victoria watched Caitlin reject Abby's genuine maternal gestures while simultaneously demanding her father's undivided focus. Love, for Caitlin, seemed less about receiving affection than about controlling it, manipulating the emotional temperature of every room she entered.

Chapter 3: Divergent Paths: College Years and Growing Apart

Harvard transformed Victoria in ways she hadn't anticipated. The scholarship that delivered her from Santa Fe also delivered her into a world where her Vineyard summers finally made sense—she belonged among the educated elite, even if she'd arrived by luck rather than birthright. Her roommate Maia represented everything Victoria had learned to navigate: privilege worn casually, assumptions about money and opportunity that Victoria had fought to earn. Meanwhile, Caitlin drifted through Europe like a beautiful ghost, collecting experiences and lovers with equal disregard for consequence. Her postcards arrived from Rome, Paris, Barcelona—cryptic messages that felt more like taunts than communications. While Victoria struggled through organic chemistry and philosophy seminars, Caitlin claimed to study art history between affairs with ski instructors and political attachés, each story more elaborate than the last. The distance between them grew beyond geography. When they spoke by phone, Victoria heard something hollow in Caitlin's voice, a performance where authentic emotion once lived. Caitlin's adventures sounded increasingly desperate rather than adventurous, as if she were running from something she couldn't name. Victoria buried herself in academic success and her relationship with Bru, the island carpenter who grounded her to earth when Harvard threatened to lift her too far from her origins. Their friendship survived through Christmas breaks and summer reunions, but the easy intimacy had shifted. Victoria now possessed the education and opportunities Caitlin had always taken for granted, while Caitlin collected experiences like souvenirs from a life she couldn't quite inhabit. They still shared secrets and laughter, but Victoria sensed Caitlin studying her now, calculating something Victoria couldn't decode.

Chapter 4: The Ultimate Betrayal: When Love and Friendship Collide

The summer after Nathan's death, Victoria fled the Vineyard mid-season, unable to bear the weight of grief and guilt that threatened to drown her. She'd left her wheelchair-bound brother to chase summer dreams with Caitlin and Bru, only to learn of his pneumonia and death through a phone call that shattered her world. The magical island suddenly felt like a punishment, every happy memory tainted by the knowledge that Nathan died while she played at being someone else's daughter. Caitlin followed her home to Santa Fe for the funeral, holding Victoria's hand through the service and staying behind to clean up after the mourners left. For once, her friend's capacity for drama served a purpose—Caitlin understood instinctively how to navigate tragedy without making it about herself. Victoria felt grateful for this unexpected gift of genuine support, never suspecting that Caitlin was already calculating how to exploit her friend's vulnerable state. The betrayal came months later, delivered casually during a phone conversation. Caitlin mentioned she'd delivered Victoria's message to Bru about why she couldn't return that summer. But something in her tone triggered Victoria's suspicions, and gradually the truth emerged: Caitlin had seduced Bru during that vulnerable time, taking Victoria's place in his bed while claiming to comfort him in her absence. The revelation felt like a second death, this time of innocence rather than family. Victoria had trusted Caitlin with everything—her secrets, her insecurities, her first love. To discover that Caitlin had used that trust as a weapon cut deeper than romantic jealousy. It suggested their entire friendship had been a game Victoria didn't know she was playing, with rules only Caitlin understood. The summer sister who once counted her pubic hairs with scientific curiosity had transformed into a calculating rival willing to destroy what Victoria cherished most.

Chapter 5: Abandonment: The Aftermath of Caitlin's Choice

Years passed like seasons in exile. Victoria built a successful career in New York public relations, married Gus, and created the stable life she'd always craved. She learned to speak of her Vineyard summers in past tense, as if they belonged to someone else's childhood. Caitlin continued her nomadic existence across continents, sending occasional postcards that felt more like evidence of life than genuine communication. When the wedding invitation arrived—Caitlin marrying Bru on Martha's Vineyard, requesting Victoria as Maid of Honor—the cruelty felt so pure it achieved a kind of artistry. Victoria's friends urged her to refuse, to finally cut ties with the woman who had consistently betrayed her trust. But something deeper than masochism drew Victoria back to the island. She needed to witness this final transformation of her past, to see if she could survive watching her first love pledge his life to her former best friend. The wedding weekend unfolded like a fever dream. Victoria found herself performing the role of gracious friend while dying inside, standing beside Caitlin at the altar as if blessing their union. The night before the ceremony, she made her own devastating choice—sleeping with Bru one final time in a hotel room that smelled of regret and salt air. If Caitlin could steal Victoria's lover, Victoria could steal back one night of what had once belonged to her. But victory felt hollow when it came. Watching Caitlin dance with Bru at their reception, Victoria realized she'd become exactly what she'd always despised—someone who took what wasn't theirs, who betrayed friendship for momentary satisfaction. The summer sisters had finally achieved perfect balance: each had now wounded the other beyond repair.

Chapter 6: Ghosts of Summers Past: Reconciling Loss and Memory

Marriage and motherhood initially seemed to steady Caitlin. She appeared to embrace domestic life on the Vineyard, playing house with Bru and their daughter Maizie in a way that almost convinced everyone she'd found peace. Victoria watched from a distance, building her own family with Gus and their son Nathan, named for the brother whose death had started this chain of betrayals. But Caitlin's performance of happiness couldn't sustain itself. Two years after Maizie's birth, she vanished as suddenly as she'd once appeared in Victoria's sixth-grade classroom. She left the baby with Lamb and Abby, abandoned her marriage, and disappeared into the European night like smoke dissolving. The woman who'd once counted pubic hairs with scientific precision had evolved into someone who could walk away from her own child without a backward glance. Victoria felt a complex mixture of vindication and horror. She'd always known Caitlin was capable of cruelty, but abandoning Maizie crossed lines even Victoria hadn't imagined her friend would breach. Yet she also recognized something familiar in Caitlin's flight—the same restlessness that had once driven her from continent to continent, as if she were searching for a version of herself that could bear to be loved. The last time Victoria saw Caitlin alive was in Venice, a carefully orchestrated reunion that felt more like a goodbye than a reconciliation. Caitlin seemed almost transparent by then, as if she were already fading from the world. They toured museums and rode gondolas like tourists rather than friends, speaking carefully around the wreckage of their shared history. When Caitlin spoke of her daughter, her voice carried a hollowness that suggested she'd already made some terrible decision.

Chapter 7: The Endless Summer: Finding Peace Among the Wildflowers

The news reached Victoria through Lamb's broken voice over the telephone. Caitlin's sailboat had been found drifting empty off the Tuscan coast, with no sign of struggle or explanation. The woman who'd once been terrified of disappearing had achieved the ultimate vanishing act, leaving behind only questions no one could answer. Victoria returned to Martha's Vineyard for what the family carefully called a "commemoration" rather than a funeral, since there was no body to bury. They gathered at sunset in a wildflower meadow overlooking the sea, the same type of vista where she and Caitlin had once sworn never to be ordinary. Now Maizie, barely five years old, scattered rose petals in the wind while Victoria held her own baby and wondered how many more secrets Caitlin had carried to whatever end she'd chosen. Afterward, alone in the meadow with the commemorative stone, Victoria finally allowed herself to rage. She screamed at Caitlin for her selfishness, her cruelty, her inability to accept love without destroying it. She wept for the girl who'd counted her pubic hairs with scientific curiosity, for the friend who'd held her hand at her brother's funeral, for all the versions of Caitlin who'd been sacrificed to feed the monster of her neediness. But she also laughed, imagining Caitlin's response to such dramatics. In the end, perhaps that was Caitlin's final gift—teaching Victoria that some friendships transcend death because they were never quite alive to begin with. They existed in the spaces between seasons, in the memory of what it felt like to be twelve and infinite, before the world taught them that summer sisters, like summer itself, must always come to an end.

Summary

Summer sisters are made, not born, in the crucible of adolescent dreams and adult betrayals. Victoria and Caitlin's friendship survived first love, family tragedy, and geographic separation, but it could not survive the women they became. One learned to accept love, the other to manipulate it. One built a life, the other performed one. In the end, Caitlin's disappearance felt less like tragedy than inevitability—the final act of someone who'd spent her life rehearsing various forms of vanishing. Yet in the wildflower meadow overlooking the Vineyard Sound, with her own children playing where she once played, Victoria understands that some bonds transcend their own destruction. Caitlin lives now in the stories Victoria tells Maizie, in the albums they page through together, in the knowledge that for one perfect summer they were infinite and invincible. The betrayals matter less than the original magic, the moment when a golden girl chose a quiet outsider for reasons that remained mysterious even in death. Summer sisters forever, despite everything—or perhaps because of it.
