Hmmm... Ok, the biggest issue I have with this story is, what makes Sam tick? And the reason for this is, there's a huge question mark about it. You see, in the beginning, we're told that when Sam's mother died, her father told her to stop crying and she's resented him ever since. We're also told that he was always asking her why she didn't do better on her grades, etc. So we get this impression that he's emotionally distant and can't be pleased. But he wants what's best for her, so the apparent emotional abuse is justified (well, at least in the H's mind - his father apparently physically abused him). So, after feeling somewhat sympathetic towards her and often wanting to smack him for more emotional abuse, we find out that well, no; her father wasn't distant and he was proud of her - she remembers things now like him playing with her and being v. happy about her graduation (what - she had amnesia?!)
So which is it - is Sam a justifiably resentful daughter who has been in a half-assed state of rebellion since she was 6, or is she just a spoiled brat?
I think the fact that the author seems to have changed her tune about dear old dad really takes away from this one. See, if you follow the entire book, and the H's insulting her at every turn, then you find yourself wondering why she wants to save her dad, only to shrug it off as a last ditched effort to seek his approval, and you also wonder why the H doesn't stop digging at her and actually think for a minute (I frankly wondered if some of the h's issues towards the H didn't stem from his getting dear old dad's approval so easily). And then, after all that, ::poof:: the h just ignored/forgot how much her daddy had been there for her and approved of her. Yeah.
And now that I've psychoanalyzed the h, and the author's motivation for a complete turnabout with regards the h and her father (yeah - nice to make me dislike dad throughout the book, then suddenly say "naw; Sam's just a bitch"), I'll give you a rundown on the story. I like time travel *to a point*. I do not like it when the time traveler is in danger of getting burned at the stake, etc. The H/h were saved at the nth hour by a miracle and someone staying the execution. Prior to that, they were pretending to be the sidhe queen and a human consort. While the motivation for this was justified, it was essentially a huge con job on poor villagers. They seemed to have few qualms about demanding better food from people who probably were doing well to feed themselves, as an example. And in between this, they were either arguing, or avoiding each other. I get that Sam was difficult. I do. I just don't think it was necessary to have them in constant conflict.
