What I remember is that it was a gothic romance. The heroine could have been a governess or housekeeper but I'm not sure. There was a clan of people that lived on the estate that was loyal to the hero and I think they were all pale. I think they only came out at night. I know they weren't vampires. There was also something about a crag. I read this in my 20's and I'm in my 50's. I either got it in a used book store or the library. I think there was a woman on the cover. I know that's not a lot of info and I'm willing to look at any suggestions. Thanks!
