We Were Liars follows the Sinclair family, a wealthy and seemingly perfect clan who spend their summers on a private island. The story centers around Cadence Sinclair Eastman, the eldest grandchild, who suffers a mysterious accident during her fifteenth summer. She can’t remember what happened, and no one will tell her the truth.
Two years later, Cadence returns to the island, determined to piece together the fragments of her memory. She reunites with her cousins, Johnny and Mirren, and her close friend Gat, who is treated as an outsider by the family. Together, they are the “Liars,” bound by secrets and rebellion against the adults.
As Cadence digs deeper, she uncovers buried tensions within the family—greed, jealousy, and the pressure to maintain their pristine image. The Liars had a pact, a plan to disrupt the family’s dysfunction, but something went terribly wrong.
Haunting visions and eerie clues lead Cadence to a devastating revelation. The accident she can’t remember wasn’t an accident at all—it was a tragedy she and the Liars orchestrated. The fire they set to reclaim their freedom ended in their own deaths. Cadence has been hallucinating their presence all along.
The truth shatters her, but it also frees her from the weight of the past. The Sinclair legacy of lies and perfection crumbles, leaving Cadence to rebuild her life with the painful knowledge of what really happened that summer.
