Jenny Han created The Summer I Turned Pretty television series, including its third season. Han is also the author of the novel trilogy on which the series is based.
The show premiered on Prime Video in 2022 and concluded with its third season in 2025. Han served as an executive producer and worked with other television writers and producers to translate her books into a serialized screen story.
Sarah Kucserka was a major creative collaborator and co-showrunner, but she is not the series creator. That distinction matters because Han originated both the literary source material and the television adaptation’s central world and characters.
