This is a good example of a typical older Regency Romance: a misunderstanding or "resistance to the truth" (either a character is resisting his/her true feelings, or there's some outside circumstance that keeps them from admitting their true feelings) that lasts for a bit more than 2/3 of the story. These characters are well written, the plot is OK, but I'm not a big fan of these kinds of novels. They pass the time, but don't linger in the memory.
