Deeply creepy with a great sense of something being slightly off at the beginning. I really like the way everything seems to be just a bit too sweet and beautiful, and how it all leaves a sort of sticky taste in your mouth. Like eating too much sugar-coated cake and custard. Or let me put it this way: Umbridge would have absolutely thrived in this world.
Bernice contributes to the story by often being the most sensible person around, while Ace is either losing control due to temper, or punching people perfectly calmly, and the Doctor of course being his usual not-gonna-tell-ya'-even-if-I-know-what's-going-on self. It's a nice little trio, that.
We also get to meet a large gallery of soon-to-be-dead characters, many pretty interesting. They all start out as walking cliches - which is exactly what they're supposed to be - but the more they see, the more they change into multi-faceted people with conflicting emotions. I especially liked the butler Garvey and his calm demeanor in the face of fear. Most characters get introduced through a mini horror story of their own, which I really enjoyed too.
Then there is the coincidence (?) of there suddenly being two Scottish doctors. Certainly quite confusing.
Despite liking most of the book, I must say I was a bit disappointed with the ending and the turn the story took in the last act. It sort of worked, and the solution also presented many interesting existential questions, the best one being: "Are we right to assume that we always know what's good and what's bad?"
It started out as such a neat ghost story and it kept on building from there, hinting at a bigger picture, but still sticking to the happy dream turned horrible nightmare-theme. I was chewing my lips, not knowing what the rules were and being terrified along with the characters involved. Then the story jumped out of that world and tried to explain it all through... well, I'm not sure how, actually. I appreciate the idea of good infecting good with the evil it has seen, and I thought that aspect of the solution did work very well. But it all turned into more of a space-opera for a while, and then there was supposed to be a grand finale in the shape of a battle. But there wasn't. Not really. Suddenly it all just sort of - ended.
Anyway, I did quite like that it turned out to be a happy ending, after all. That definitely isn't always the case. And this time it did kind of bookend (difficult to end a book with anything but a bookend, but still) the whole thing, considering it started out with a false happily-ever-after, and ended with something similar, except real.
