I have to think this isn't one of Beverley's best. I don't need a lot of plot in the books I read, but this one had so little plot movement that even I eventually grew a bit restless. I got the impression Beverley was more invested in the love story of the long-lost heir and the cabin boy (their names have not stuck with me, though I remember they nicknamed one another Othello and Desdemona) than in the central romance.
But as I said, her language is excellent and you get the sense that she really knows her Regency history details. I'll have to do a little backlist research and read one of her better-loved books.
