There is a We Were Liars show now: it is a TV adaptation of E. Lockhart’s YA novel, released as a mystery‑drama series on Prime Video in 2025.

What the show is about

  • The series follows Cadence Sinclair, heir to a wealthy New England family who spends summers on a private island, Beechwood, with her cousins and love interest Gat.
  • After a mysterious accident, Cadence suffers memory loss and migraines, and slowly pieces together what really happened during a previous summer, uncovering dark family secrets, class tension, and a tragic crime.

Format, release and where it’s streaming

  • We Were Liars is produced as a TV series (not just a movie) and is streaming on Prime Video , positioned as a dark, emotional YA thriller.
  • The tone is marketed as “Big Little Lies meets Outer Banks,” with an emphasis on privilege, a creepy island atmosphere, and a gut‑punch twist faithful to the book’s big reveal.

How close it is to the book

  • The show keeps the core elements: the Sinclair family’s toxic perfectionism, the tight‑knit group called “the Liars,” the fire at the mansion Clairmont, and the late‑season twist about what really happened to Cadence’s friends.
  • Some plot beats and character moments are expanded or shifted for TV (for example, the inheritance games and lemon–lime hunt, and more screen time for side characters), but the overall mystery and emotional ending remain aligned with the novel.

Cast and current fan chatter

  • The main ensemble includes young actors like Emily Alyn Lind and others in the central “Liars” group, who have been doing promo games and interviews talking about fan edits and YA‑drama vibes.
  • Online discussions in 2025–2026 focus on:
    • Whether the twist still “works” if you already know the book
    • How intense and potentially traumatizing the ending feels for Gen Z audiences
    • Comparisons to other book‑to‑screen YA hits and whether the show captures the original’s haunting tone.

TL;DR

  • The We Were Liars show is a Prime Video YA mystery series released in 2025, adapting E. Lockhart’s bestselling novel with a dark island setting and a devastating twist.
