This was a reasonably good regency romance. There were two issues for me: One, the tendency of both hero and heroine to assume the worst on the flimsiest of evidence; and two, there were some issues with improper address. A huge pet peeve of mine is the improper use of titles when addressing those of rank. If you want to write period pieces, you very much need and are expected to know the manner of polite address. If you are introducing a duchess, for instance you would refer to her as, "Her Grace, the Duchess of Wellesley." The Queen of England and all her other titles would be simply, "Her Majesty, the Queen." When chatting up a duchess, you would not say, "Duchess, would you care for tea?" She would be addressed as, "Your Grace." Also, using references to title too much in conversation would be considered questionable, unless one was being a properly deferential servant.
