After a late-night accident leaves Anna fighting for her life, she wakes to find herself trapped in a hospital that isn't the one she remembers. The halls stretch too far, the lights flicker without reason, and something in the darkness knows her name.

As she searches for a way back to the world of the living, Anna discovers she is caught between life and death ? and she is not alone. A shadow known only as the Reaper waits in the corridors, hunting those who are not meant to return. With the help of a mysterious woman who seems to know this place too well, Anna must outrun the thing that wants her soul before the door back to life closes forever.

But surviving the hospital is only the beginning.
When Anna finally wakes, the nightmare doesn't stay behind. Strange sounds echo through her apartment, shadows move where nothing should be, and the past of the hospital reveals a terrible secret buried beneath its walls.

Something followed her back.
Something that has been waiting for a very long time.

In The One Who Waits in the Dark, the line between the living and the dead is thinner than anyone believes ? and once something sees you on the other side, it may never let you go.
