Olivia Sherwood has fallen on hard times. Her father was murdered a year ago by a gypsy, and her sister, who witnessed the murder, has gone blind. Olivia is forced to work at the home of the Earl of Ravenwood, despite being a gentlewoman. She has been hired because the new Earl is coming to visit, and the house needs to be prepared - as does the village. It's well known that the Earl is the bastard son of the previous Earl and a gypsy woman, and rumors of his raking in London have reached the village.

When Olivia meets Dominic St. Bride, she discovers that he is a complex man but perhaps not the devil he has been painted to be. As she gets to know him, she finds a great deal to like about him. Unfortunately for Dominic, there are those in the village who want to drive him out. Can the villagers get past their antipathy toward the gypsies, even when some children are kidnapped?

One Moonlit Night is an enjoyable read despite the fact that most of the ideas and scenes have been explored before in this kind of novel. As well as Olivia's romance with Dominic there was a sub-romance with Olivia's blind sister which is rather touching. Occasional lapses of historicity occur, particularly within the dialogue, and Olivia's behavior is sometimes surprising in a woman brought up the way she must have been, particularly regarding her understanding of what is acceptable behavior, but it's still a good read with a few insights into the gypsy life.
