What do you expect from a thriller with supernatural elements? Of course, you want a story that makes you turn the pages, keeps you on the edge of your seat and say to yourself, “I’ll read just one more chapter before I go to sleep.”
And what about the supernatural in such a story? Do you expect ghosts? Vampires? Other denizens of the Other? Or are you looking for a novel whose atmosphere points to something bigger, more wondrous, perhaps more dangerous, than the world which we inhabit?
