The book was inspired by a dream I had last year. Originally, it was going to be a completely different story, more faithful to the dream. Originally, it was going to be a Young Adult science fiction adventure story, with time travel, black holes and starships and such. But once I had the original story plotted, I didn't really like it and couldn't motive myself to start writing it. So I started shifting things around, and somehow, it turned into the sort of supernatural, haunted house, ghost story romance that it is now. About the only thing that remains of the original dream and idea is the house and its passages to alternate realities.
