The Unknown

The Unknown by Riley Sager is a chilling mystery set on a remote Vermont island where five women vanished without a trace in 1926—and, one hundred years later, the disappearances begin again. When actress Marin Keane arrives to film a movie about the island’s dark history, strange symbols, unsettling sounds, and a decades-old diary make it clear that New Avalon may be hiding something far more sinister than a forgotten crime. Atmospheric, twisty, and deeply creepy, this is a perfect read for fans of haunted places, locked-room mysteries, unreliable histories, and secrets that refuse to stay buried.
