Jean MacDonald and her sister, Catriona, have had some sort of scandal in their pasts that have led them to the Scottish Highlands where they are now working as maids for Morgan MacCraig, who has been away from his castle for years. As the story opens, Jean is hiding out in one of the castle's rooms, looking for ghosts. As a beginning, I have to say my attention wasn't quite arrested. In fact, the story started rather slowly for me, and I was a bit put off by the ghost aspect (paranormal romances aren't quite my thing, and this isn't a pnr, but you wouldn't know that from the opening).
When he first (literally) runs into Jean, Morgan MacCraig immediately notices that Jean is no ordinary maid. She's quite plain (he somewhat endearingly at first, then annoyingly as he continues, thinks of her as a little "wren"). He's fascinated by her outspokenness and her interest in his family's ghosts. At this point, the story takes off a bit. Morgan and Jean have several run-ins as she is looking for ghosts (in the middle of the night, of course, because she has to attend her maid duties during the day). I enjoyed these encounters because, while they seem wholly implausible conversations for a lord and maid of a castle, they revealed the characters of the H and h and developed sexual tension.
Unfortunately, I don't think I entirely cared for Morgan's character. I think he was intended to come across as a bit of a tortured hero, but instead, when he thinks about his ex-wife and how she cuckolded him and how society has turned its back on him for obtaining a divorce, and when he acts so passively toward his friend Andrew (a self-aggrandizing-womanizer), I tended to think of him as weak. I wanted him to develop more of a backbone with Andrew and to demonstrate stronger character and drive than what he does as the story progresses.
And while Jean was first described as plain, I became increasingly annoyed by her perfection. She was always making things right for Morgan, and it added to my view of him as a weak character while at the same time making her seem a bit over-the-top. Likewise, there was virtually no action in the book. I think a good brawl or a less obvious drama involving Andrew and Catriona might have worked better, but the plot is so open and obvious, there really wasn't a compelling reason to get to the end of the book except to merely finish it. Even the quasi-mystery of Jean and Catriona's family background is pretty obvious at the third or fourth mention of it, so there's not even a compelling mystery.
