Every summer, Cadence reunites with her close-knit group of friends and cousins—collectively known as “the Liars”—for what should be idyllic months of sun, swimming, and freedom. But beneath the surface of privilege and perfection lies a dark secret. After a mysterious accident leaves Cadence with memory loss and lingering pain, she returns to the island determined to uncover the truth. What really happened that summer? And why does everyone she loves seem to be hiding something?
