One day, Marion wakes up in her attic. Odd—she doesn't really recall falling asleep there. Soon, she realizes that someone else—a girl—is living in her house. But she's never met her before! And although her village is similar to the one she's grown up in, it is not identical. And neither are the people.

Marion is now adrift in a world that feels familiar, but is filled with strangers.
What is this place? Who are these people? And where is her fiancé?
