Lord Andrew de Montforte, the defiant one, is a man of science. He accidentally discovers an aphrodisiac; unfortunately, he can't recreate it. Lady Celsiana Blake is an animal activist and an heiress. Lucien, the Duke of Blackheath and Andrew's manipulative older brother, decides that Andrew and Celsie will make a perfect match - and to get them together, he allows Celsiana to believe that Andrew is conducting experiments on dogs. Gerald, the Earl of Somerfield and Celsie's brother, is almost destitute and intends to have control over his sister's vast fortune by handpicking her husband. Meanwhile, Lucien does everything in his power to bring the two reluctant characters together. So far so good, right? Except that there are parts of the plot that are unbelievable and out of character for the setting (Georgian time); just as the occasional modern word ruins the feeling of immersion in the time setting and the book itself.
