'Remember daughter, the world is a lot bigger than anyone knows. There are things that science may never explain. Maybe some things that shouldn't be explained.' Stacey and Laney are twins – mirror images of each other – and yet they're as different as the sun and the moon. Stacey works hard at school, determined to get out of their small town. Laney skips school and sneaks out of the house to meet her boyfriend. But when Laney disappears one night, Stacey can't believe she's just run off without telling her. As the days pass and Laney doesn't return, Stacey starts dreaming of her twin. The dreams are dark and terrifying and hard to shake. Stacey can't tell what's real and what's imagined. All she knows for sure is that Laney needs her help. Stacey is the only one who can find her sister. Will she find her in time?
