This is an excellent book which recounts the further adventures of Mistress Martha Morgan of Plas Ingli -- who is now firmly establishes as one of the most interesting heroines in recent historical fiction. Move over, Elizabeth Bennett! Really this tale, set in the early 1800's, is about love lost and regained, and while the story is dominated by a mysterious figure in black called "The Nightwalker", and by the heroine's self-doubts and periods of depression, this novel is really about constancy and the triumph of love. As in the earlier novels, the plot twists and turns and rushes ahead at a fine pace, and once again the author packs a double whammy into the final few pages of the book.
