In a haunting novel of psychological suspense, a summer getaway gone wrong rips apart a group of lifelong friends, thrusting their story into the true crime spotlight--and potentially their secrets, too.

For five friends vacationing on Block Island, it's a summer to remember. How can they forget it when only four make it back to the mainland? One vanishes without a trace. A friendship is changed forever.

Five years after Zoe Gilbert's disappearance, Callie Sutter invites her estranged friends to reunite on the anniversary of the mystery that tore them apart. Back on Block Island, they can come together again, memorialize Zoe, allay old resentments and recriminations, and put the past to rest. It won't be easy. A true crime podcaster is most eager for the reunion. She's made a name for herself by casting suspicion on Zoe's friends, and threatens to expose them all as cold-blooded liars and conspirators in a crime.

Driven by self-preservation, Callie and her friends must reckon with their long-held secrets and shared history if they're to find out what really happened to Zoe on that hot August day. No one is prepared for the truth.
