Kyra Sedgwick and Elsie Fisher will join the second season of The Summer I Turned Pretty, the Amazon Prime series based on Jenny Han’s book, Deadline reports.

Sedgwick (Something To Talk About, Singles) and Fisher (Eighth Grade, Texas Chainsaw Massacre) will have recurring roles, as yet unspecified, in the series. They join a cast that includes Lola Tung, Jackie Chung, and Rachel Blanchard.

The series is based on Han’s 2009 young adult novel about a teenage girl who spends summers with her family and friends at a beach house. A critic for Kirkus wrote of the book—the first in a trilogy—“The wish-fulfilling title and sun-washed, catalog-beautiful teens on the cover will be enticing for girls looking for a diversion.”

The show was renewed for a second season before the first one even aired. Amazon’s confidence in the series proved to be well earned; it became the most-viewed show on the streaming service shortly after its release.

Sedgwick announced her casting in the series in an Instagram post, writing that she “couldn’t be more excited” to join the show.

The post was accompanied by a video showing someone knocking on a trailer door with the name “Skye” on it. Fisher opens the door and does a brief dance before the camera pans over to Sedgwick, who’s reading a copy of Han’s It’s Not Summer Without You.
