The White Room: Dove

Dove, a 16-year-old girl wakes up in a white room with absolutely zero memory of how she got there.

Cozbi, the man in charge of her, allows Dove to do whatever she pleases, with only two rules.
(1) She can not leave the room.
(2) and she can not let anyone into the room.

When Cozbi stops showing up one day, Dove opens the white door and steps out into the dark hallway.
