I just finished reading Dan Simmons "A Winter Haunting" and oh, my gosh, it is spooky! I ended every chapter with a cringe, a glance over my shoulder, and a nervous little laugh.
I don't normally jump at house sounds in the night, but I did while reading this book, and in addition, I checked and re-checked to make sure the house alarm was activiated. (Not that an alarm would have scared away any of the malevolence in THIS book.)
Dan Simmons has skillfully blended reality with unreality, so that it ALL seemed real. Mysterious messages appearing on the computer screen, strange lights and noises in the boarded up second story of an abandoned house, the sudden appearance and disappearance of a stray dog, an overwhelming sense of danger, and all of it overlaid with the cold and gloom of a midwest winter.
