This is the kind of writing that the word ambiance was created for. You gave me creepy shivers with your descriptions of the house.
And I loved how Andy suddenly wasn't so sure hewanted to get inside that head of hers. It just made him seem so, well, human!
Leave me hanging much? Can't believe you ended it there. Well, actually I can because you are really so good at leaving your reader wanting more.
So updates STAT, please xx
