Coraline is a dark fantasy created by author Neil Gaiman. It was adapated into a graphic novel (2009) and an animated feature (2009).
Coraline is a young girl who moves into a new home with her parents and feels out of place. Her parents don't seem to have too much time for her, so she goes exploring and meets some of her odd new neighbors and the neighborhood cat. One night, she discovers a hidden doorway that leads to a parallel world; it's here that she meets her "Other Mother", who seems to have all of the time in the world for Coraline and always makes delicious meals. She desperately wants Coraline to stay, but there's something... strange... about the Other Mother. As Coraline visits more often, she discovers that the Other Mother is not at all what she seems, and she'll need the help of the neighborhood cat - who isn't exactly what he seems, either - to save herself and her family.
