What Happens in This One Summer: Full Plot Summary

The whole story of This One Summer (2023) explained, from the opening scene to the final frame: every key event, every twist and what it all adds up to. Read it as a quick recap before the sequel, to check a scene you missed, or to finally understand what really happened.

Every summer, Rose, Rose Pou Pellicer, returns to a cottage in Awago where she and her friend Windy spend long days and nights testing the edges of growing up. Rose is about eighteen months older than Windy, and she serves as the story’s narrator, quietly guiding us through their observations and questions as the days unfold.

As the girls begin to explore their budding interest in boys, they also start paying attention to the emotional lives of the adults around them. The village forms a kind of rogues' gallery of sad and burnt-out would-be role models, a backdrop that sharpens the girls’ own curiosity and sense of what adulthood might look like. Rose’s growing awareness is sharpened by a troubling realization about her mother, Alice, who is dealing with depression following infertility issues. The tension at home thickens, and Rose’s frustration boils over one night as she yells at Alice, blaming her for the family’s reluctance to go to the beach and for the arguments with her husband, Evan, who leaves for the city for several days.

In Awago, the girls also meet Jenny, a teenager who has unexpectedly become pregnant. The news unsettles the community, and after a heated argument with the father of the child—who has ignored both Jenny and the baby since the revelation—Jenny drinks, and Alice steps in to save her from a desperate act by attempting to drown herself. The encounter casts a harsher light on the fragility of the relationships surrounding them and deepens Rose’s sense of responsibility and worry.

The book’s close returns to the core cause behind Alice’s marital and emotional troubles: a miscarriage she endured in a lake the summer before, right there in Awago. As Rose and Windy’s mothers recount the events, the story settles into a sober reflection on loss, memory, and how early life’s shocks ripple through families. What began as a summer of innocent questions about romance and friendship becomes a quiet meditation on grief, resilience, and the ways people cope with pain while trying to protect the younger generation from repeating the same hurts.
