The highly-anticipated third and final season of *The Summer I Turned Pretty* has finally arrived, bringing Belly, Conrad, and Jeremiah’s iconic love triangle to a dramatic conclusion. Based on Jenny Han's third novel, *We'll Always Have Summer*, the final 11-episode season premiered on Wednesday, July 16, 2025, with the first two episodes dropping simultaneously on Prime Video. This season not only sees the return of all your favorite characters but also introduces a wave of fresh faces set to shake up the dynamics in Cousins Beach, confirming the series' commitment to delivering a faithful yet surprising adaptation of the beloved book trilogy.

The stakes are higher than ever as the story jumps forward two years, finding Isabel "Belly" Conklin newly 21 and facing the biggest decision of her life: which Fisher brother—Conrad or Jeremiah—truly holds her heart? With filming having wrapped in North Carolina over the summer of 2024, the cast is ready to deliver the emotional final chapter, and we have the complete guide to every returning star and the new actors joining the definitive love story of the summer.

The Returning Main Cast: The Fisher-Conklin Core

The heart of *The Summer I Turned Pretty* lies in its core ensemble, and thankfully, all the key players are back for the final season. Their return ensures that the emotional weight of the series' conclusion—which will cover Belly's college years and a pivotal wedding—remains intact.

  • Lola Tung as Isabel "Belly" Conklin: The protagonist whose journey from a shy teenager to a confident young woman is at the center of the series. Season 3 finds Belly older, navigating college life, and still caught between the Fisher brothers.
  • Christopher Briney as Conrad Fisher: The brooding, emotionally complex older Fisher brother. His relationship with Belly forms the central conflict of the final book, which sees him dealing with the aftermath of his mother's death and his own academic future.
  • Gavin Casalegno as Jeremiah Fisher: The charming, golden-retriever younger Fisher brother. Jeremiah's storyline in Season 3 involves a significant life event that forces Belly to confront her true feelings.
  • Sean Kaufman as Steven Conklin: Belly's older brother. Steven's relationship with Taylor is a major secondary plot that fans are eager to see resolved.
  • Rain Spencer as Taylor Jewel: Belly's best friend and Steven's on-again, off-again love interest. Taylor's role has expanded significantly from the books, making her a vital part of the ensemble.
  • David Iacono as Cam Cameron: Belly's sweet, brief boyfriend from Season 1. While his character's role in the third book is minimal, his continued presence in the series offers a familiar face.
  • Jackie Chung as Laurel Park: Belly and Steven's mother, Susannah's best friend, and an author grappling with her own life changes.
  • Minnie Mills as Shayla: While Shayla's return was initially uncertain after Season 2, fans are hopeful to see the continuation of her story, especially in relation to Steven.
  • Kyra Sedgwick (Aunt Julia) and Elsie Fisher (Skye): Notably, Kyra Sedgwick, who played Aunt Julia, confirmed she is *not* returning for the third season, meaning the storyline revolving around the sale of the Cousins Beach house is likely resolved.

Meet the New Faces: Series Regulars & Recurring Characters

The final chapter of the series is set to introduce several new characters, many of whom are expected to be key players in the adaptation of *We'll Always Have Summer*. These additions will introduce new romantic rivals, college friends, and professional connections for the main cast, significantly expanding the world beyond Cousins Beach.

New Series Regulars

Two actors have been officially confirmed as new series regulars for Season 3, indicating their roles will be central to the season's 11-episode arc.

  • Isabella Briggs as Denise: Briggs, known for her work on *Sugar*, joins the cast as Denise. Her character is a new addition to the show's universe and is expected to be a significant figure in Belly's college life or the larger social circle.
  • Kristen Connolly as Lucinda Jewel: Connolly, a veteran actress from *House of Cards* and *The Cabin in the Woods*, is set to play Lucinda Jewel. Given the character's last name, some fan theories suggest she may be related to Taylor, or play a role in the wedding plot line central to the book.

New Recurring Players

A host of new recurring cast members will complicate the lives of the core group, bringing fresh drama and new romantic possibilities.

  • Sofia Bryant as Anika: Bryant is confirmed to play Anika, a new character whose role is likely tied to the college setting of the third book, potentially as a friend or rival.
  • Lily Donoghue as Lacie Barone: Donoghue, who appeared in *Daisy Jones & The Six*, joins the cast as Lacie Barone. Lacie is another new entity who will be part of the expanded social dynamics this season.
  • Zoé de Grand’Maison as Agnes: De Grand’Maison will portray Agnes. New characters like Agnes are often introduced to challenge the existing relationships, especially the "Team Conrad" vs. "Team Jeremiah" dynamic.
  • Tanner Zagarino as Redbird: Zagarino's character, Redbird, is another new face whose presence will stir up more drama for the main characters.
  • Emma Ishta: Ishta joins the recurring cast, though her specific character name has not yet been officially confirmed. She is expected to be a key figure in the new social landscape of the show.

The Final Summer: What to Expect from the Plot and Topical Authority

The third season is based on the final book in Jenny Han's trilogy, *We'll Always Have Summer*. The transition from the high-school drama of the first two seasons to the college and early-adulthood setting of Season 3 is a major shift that significantly impacts the cast and plot.

The season is expected to tackle mature themes, including long-distance relationships, college life, and the reality of making permanent life choices. The central conflict will revolve around a major event—a potential wedding—that forces Belly to finally choose between Conrad and Jeremiah. This pivotal moment is the ultimate payoff for fans of the "Belly's Choice" narrative. The show's commitment to adapting this final book, especially with an 11-episode run, suggests a detailed exploration of the book's emotional beats, including the infamous *infinity* necklace and the ultimate resolution of the love triangle.

Topical authority is further bolstered by the inclusion of numerous new entities related to the book's themes: college life, long-distance relationships, the concept of a "soulmate," the Cousins Beach setting (which remains a central entity), and the emotional legacy of Susannah Fisher.

The Shocking Post-Series Feature Film Announcement

In a massive surprise for the fandom, Prime Video announced a feature-length film to follow the conclusion of the series. The film, which was announced on September 17, 2025, is a major development that extends the franchise beyond the three-season arc. This unexpected movie suggests that while the main love triangle may find its resolution in the final episode, the lives of Belly, Conrad, Jeremiah, Steven, and Taylor will continue, potentially exploring their lives a few years after the events of the final season. This news provides a fresh and unique angle for any discussion about the cast, as it implies that the actors may not be saying goodbye to their characters just yet.
