There are some unfortunate things in this book. Bizarrely the characters play tennis in January in a snow-covered Cumbria and are ready to have lunch outdoors. The author seems to think that Land's End is a village and doesn't know that Cumbria has a lot of coast. There are also some continuity errors - the heroine seems able to move her hands even when they are pinned above her head and one minute the earl isn't wearing his coat and the next minute he takes it off to wrap Olivia in it.
There are also some odd errors that I presume are limited to the Kindle edition.
Overall it's a good romance and the hero and heroine are well-drawn. The plot is not obvious and the conclusion is satisfying. For once the ghost story moves the plot along, rather than causing it to stop.
