Lockhart, We Were Liars, the series follows Cadence Sinclair Eastman and her tight-knit inner circle, nicknamed the Liars, during their summer escapades on her grandfather’s New England private island. The Sinclairs are American royalty — known for their good looks, old money, and enviable bond — but after a mysterious accident changes Cadence’s life forever, everyone, including her beloved Liars, seems to have something to hide.
