But Lauren knew fear.

Inside--voices entreating her to love them.

Outside--the mystery of the missing group that had gone before her. The dead group.
But were they simply dead?

Or something else?

A terrifying novel of horror--and, surprisingly, of salvation--from one of America's bestselling writers.

A novel you won't forget.
