i'm looking for a movie from the 70's or 80's or 90's.
It starts with a murder in cabin and a broken snow globe.The husband kill the wife and the son watches.
Later the cabin is visited by teens. I think the son returns with them.
The cabin looks broken from the outside but when they enter, the cabin looks intact.
Later they are attacked by zombies/demons, I don't remember well.
I remember there is a book involved, but I'm not sure.
The final scene is the main couple leaves the town but leave the book and a zombie/demon girl (face full of maggots) picks it up.
Any help identifying the movie will be great.
