Hello everyone. I am looking for a book I read here on wattpad like 3 years ago. It is about a girl who moved to a new place with her mom and I think they lived in California before. and the place they moved to was full of mystery and horror. And I remember this one part where a part of her wall was taken down because she realized that it wasn't really a wall but an opening to a small room where she made into a painting room I think. So she had a neighbor next door, a guy, and they became a couple afterwards. And if I remember correctly, this guy has a little sister who sneaks out at night to play with a little girl who was a ghost and the main character saw her on her window a few times. And together with her bf and their friends they explore stuff about the town. I have read the ending which was like letting the little ghosty girl rest with her parents and burning the haunted barn or I think it was burned by the bad ghost. This story has like 2 or 3 books and the title was something like the house hill or something. And the cover which may or may not have changed that I remember was a view of a house on a hill I think and it was foggy.
