Amazon Prime Video announced the first cast members on May 15, 2026, for the upcoming Irish young adult series “Boys of Tommen” [1].

The announcement signals Amazon's intent to expand its library of youth-focused original content by adapting a popular literary property [2]. This move targets the high-growth demographic of young adult readers and viewers who have driven the success of similar romantic dramas [2].

The series is based on the book series by Chloe Walsh, which is a No. 1 New York Times bestseller [4]. The production is being handled by WIIP, the same studio responsible for the hit series “The Summer I Turned Pretty” [1, 3].

Nancy Surridge will lead the cast as the character Shannon Lynch [6]. Other early casting reveals include Conor Sánchez [1], who will join the ensemble in the romantic-drama adaptation [1].

While specific plot details remain under wraps, the series will be an original production for Prime Video [1]. The show will bring Walsh's bestselling Irish narrative to a global streaming audience, leveraging the studio's experience with YA storytelling [2, 3].

Prime Video has not yet released a premiere date or a full cast list for the production [1]. The company continues to lean into the “book-to-screen” pipeline to secure built-in audiences for its original programming [2].

“Boys of Tommen” is based on a No. 1 New York Times bestseller

The adaptation of 'Boys of Tommen' reflects a broader industry trend where streaming platforms prioritize established intellectual property with existing fandoms to mitigate the risk of original content. By partnering with WIIP, Amazon is doubling down on a specific aesthetic and narrative style that resonated with audiences in 'The Summer I Turned Pretty,' aiming to capture the same emotional and demographic appeal within the Irish YA setting.
