Irwin’s debut is charming, if a bit paint-by-numbers, recalling Georgette Heyer and other classics of the genre. In contrast to recent trends in historical romance, the hero and heroine don’t do much more than kiss on the page, and their romance develops quite late in the story; much of the plot focuses more on Kitty and Cecily’s introduction to the layers and intrigues of 1818 London. But it isn’t all Austen-esque; Kitty’s honesty about her aims, and Radcliffe’s acceptance of them, allows the story to suit modern sensibilities without sacrificing too much of the vintage feel ... A sweet Regency debut for contemporary fans of classic romance.
