We Were Liars, by E. LockhartRead about the other entries on the list.
Everything changes for Cadence Sinclair during her fifteenth summer at her family’s beach. As Cadence struggles with memory loss, physical injuries, and a secret that no one is willing to share, she is also growing into adulthood. After spending the next summer in Europe, and then finally returning to the family’s beloved summer house on the island, Cadence has to face some harsh realities about herself and her cousins. In much the same vein as the twisty Gone Girl, readers will find themselves by turns sad, frustrated, amazed, and shocked. It’s nearly impossible to read this book without having some strong feelings, and a movie adaption would be irresistible.
We Were Liars is among Ruth Ware's top ten psychological thrillers and Meredith Moore's five favorite YA thrillers.
