The Unknown Audiobook by Riley Sager— narrated by Riley Sager, Maggie Grace, Patricia Santomasso, and Erin Lin

Riley Sager's The Unknown drops a film crew on the Vermont island where five women vanished in 1926, then dares the cast, and the reader, to decide if the new disappearances are sabotage or something the island never let go of. It's a gothic thriller that trusts its central image enough to make you sit with it before the killing starts again.

Why the audiobook wins

Riley Sager, who wrote the book, is one of four narrators, along with Maggie Grace, Patricia Santomasso and Erin Lin. That is a lot of voices for a gothic thriller that alternates present-day chapters with the 1926 diary of Daisy Rue, one of five women who vanished from a Vermont island.

The book builds slow dread that pays off late. The middle sags a little before the final act tightens, and the cast is an ensemble of suspects and victims at once. The question of sabotage or something supernatural stays open for a long time, which suits a dark evening of listening.

One Audible credit covers the whole book.
