The book series "The Summer I Turned Pretty" consists of three books: "The Summer I Turned Pretty," "It's Not Summer Without You," and "We'll Always Have Summer." Han told Entertainment Weekly that the first season covers the first book and that she hopes to make two more seasons covering each of the sequels.
"Originally, 'The Summer I Turned Pretty' was supposed to be just the one book, but I wanted to spend each summer of her life with her in that story," Han said. "When I started writing it, I realized I needed more space to tell the story. I feel the same way about TV — I think that novels actually lend themselves really well to TV, because you just get a lot more time to really delve into the characters and be with them on their journey."
Well, her wish came true, because Prime Video renewed the show for a second season ahead of its premiere. "When I decided to adapt summer for television, I knew we'd need more than one season to honor the story we are telling," Han said in a press release. "To receive a second season pickup ahead of the premiere of season one is beyond my wildest dreams. I am so grateful to Amazon Studios for this amazing vote of confidence in our show, and cannot wait to bring our incredible team back together to tell the next chapter in our story."
