I'm still not quite sure what I thought of this. I had heard the ending was shocking from other readers so wasn't totally sideswiped, but it was still a very interesting take on what originally seemed like a romance book.
I suppose one would call it a paranormal suspense novel? I've yet to figure out what was real interaction, remembered past and paranormal activity - perhaps that will be clearer on a second read through.
All told, I did enjoy the storyline even with the uncertainty of what was actually going on.
