This is undoubtedly one of Kirkland's best, in characterization, plot, and flow. The hero and heroine are conscientious, kind, truth to themselves, and easily earned this reader's heart.
Matthew Donaldson believes himself not a gentleman for his many years in the war, and having unexpectedly come to the inheritance of a large estate - the old Donaldson had suddenly disinherited his long-time heir, Matthew feels a duty to treasure the precious art collection assembled by generations of Donaldsons - which is where Sarah Sterling comes in, to work as art restorer on behalf of her sick father. Sarah came all the way from London to Northumberland and is quickly taken with the wild beauty of this land, the wondrous art collection, and its perplexingly kind owner. Throw in an art theft mystery, a brief secondary romance between two of Matthew's cousins (one of them being the disinherited heir), and you have there both a wonderful romance and an intriguing mystery without any annoying side characters or loose plot ends.
I also found the banter and puns in the book much to my liking, as both Sarah and Matthew are very intelligent, and to my great relief, the appearance of what seemed to be another matron pushing her daughter at Matthew for his wealth ended up without much drama and nefarious schemes - as is the norm with such characters in these kinds of books - so the romance is quite unhindered and left to develop slowly on its own without misunderstandings or really, any frustration.
The mystery element is nicely done, as well, with an obvious red herring from the start, although the discerning reader would have picked up on the culprit ages ago. Even so, our characters are smart and the villain is just at the right intelligence level with a sound reason for his crimes, so I enjoyed the progress made on this front albeit having long guessed at the villain's identity.
If you enjoy traditional regencies, this is definitely a book you don't want to miss.
