Jenny Han, author behind "The Summer I Turned Pretty" series, on how Taylor Swift's music played a role in her writing

Bestselling author Jenny Han, who is known for a series of beloved young adult novels, is now a showrunner for a new Prime Video series inspired by her famous trilogy "The Summer I Turned Pretty."

Han not only helped create the TV series, but she had a hand in its hit soundtrack, which includes songs from Cardi B, Olivia Rodrigo, Taylor Swift and other big names. Swift's music, in fact, has long played a role in Han's writing process, she said Monday on "CBS Mornings."

"I've been a fan for years. As I was writing the books, I was listening to her music," Han said, adding that Swift's music brought her the emotion she needed to tap into during her writing.
