Angsting over moving to a new town and school, Mina finds herself thrown into an alternate world that makes her past problems fade into the shadows as new worries arise. Without a familiar face in sight, Mina makes the long journey from pouting to desperate survival with a young girl as lost as she is, and a teen boy finding his own way in the world of shadows.
