Adeline Withers is a normal girl. Well, as normal as she can get, of course. She likes people, yet she's not social. She likes dancing, yet she's never been to a party, or to a club, or... You get the point. Now, here's the not-normal part of her life. She has no idea where her parents are. She's always alone, and she's always looked out for herself. But she can't help but feel a little bit lonely, even if she has the bestest friend she could ever hope for. All things change though, when she goes on the bus home from school. She's seen some weird things and she's afraid she's losing her sanity by the minute.
