I remember reading many years ago a story about a young girl who is in a very old, very large house or something, and she finds this old book and she gets sucked into it into a fantasy land. Beyond those details I can't remember much else though. I know it sounds a lot like the Neverending Story, but that's not it. Thanks guys!
Maybe Coraline, by Neil Gaiman?
… a story about a young girl who is in a very old, very large house or something, …
Coraline Jones and her parents move into an old mansion …
… and she finds this old book and she gets sucked into it into a fantasy land.
One rainy day Coraline discovers a locked door ….
… Coraline decides to unlock the door ….
… a long hallway that leads to a flat identical to her own but inhabited by the “Other Mother” and “Other Father”. They seem to look like her parents, except that in place of eyes, they have shiny black buttons. …
Another story with a girl entering the world of a book is Inkspell, the second volume of the Inkheart trilogy by Cornelia Funke.
