This summary of The Summer I Turned Pretty by Jenny Han centers on fifteen-year-old Isabel "Belly" Conklin, who narrates the story. Every June, Belly travels with her mother, Laurel, and older brother, Steven, to Cousins Beach, where they spend the summer at the beach house of Laurel's lifelong best friend, Susannah Fisher. There, Belly reunites with Susannah's two sons: the older, moody Conrad, on whom she has had a lifelong crush, and the warmer, more easygoing Jeremiah, her close friend. As Belly puts it, her whole life is "measured in summers."

This summer, everything feels different. Belly has grown up and "turned pretty" over the past year, and for the first time both Fisher brothers, and other boys, see her as more than just somebody's little sister. Belly begins dating a sweet lifeguard named Cam, but her long-standing feelings for Conrad simmer beneath the surface. Conrad, meanwhile, has become distant and troubled, drinking and withdrawing, which strains his friendship with Steven and puzzles everyone.

As told in this The Summer I Turned Pretty summary, romantic tension builds throughout the season. Jeremiah surprises Belly by confessing that he has developed feelings for her, which forces Belly to confront her own heart. Realizing she can no longer deny her love for Conrad, she tells him how she feels, but he rejects her, triggering a painful fight between the two brothers.

The emotional turning point comes when Belly discovers the secret that has been quietly shadowing the whole summer: Susannah's cancer has returned, and this time she is not expected to survive. This revelation reframes everything, Conrad's moodiness, the tension in the house, the sense that this idyllic world is slipping away. Belly shifts her focus from romance to supporting the grieving Fisher family, comforting Jeremiah, promising Susannah she will look after Conrad, and being there as Conrad breaks down over his mother's illness. In a tender, bittersweet moment, Belly and Conrad share a kiss, though he admits he is too devastated to begin a relationship, setting up the emotional close of the novel.

The Summer I Turned Pretty ends on a bittersweet, hopeful note. As the summer draws to a close, the shadow of Susannah's returning cancer hangs over everyone, and she decides to suspend her treatments to focus on enjoying the time she has left. On the last night at the beach house, Belly invites Conrad and Jeremiah for a midnight swim, and the three of them recite Susannah's favorite poem and spin together in the pool, briefly recapturing the innocence of childhood summers, even as they sense this era is ending.

Belly and Conrad have shared a kiss, but Conrad, overwhelmed by grief over his mother, tells Belly he cares about her but isn't ready for a relationship. Belly understands, and the two families pack up and leave Cousins Beach, uncertain what the future holds.

The novel then jumps forward to winter. Several months later, Conrad drives from Boston to Belly's house in the middle of the night. Belly sneaks out to meet him, and she gets into his car, suggesting that a relationship between them may finally be beginning. The conclusion of this summary of The Summer I Turned Pretty leaves readers with a tender sense of possibility, first love tentatively taking root, while the looming loss of Susannah adds poignancy, setting the stage for the trilogy's next book.
