Dorothy Hartfield, a marquise residing in the great kingdom of Napier, has had a dislike of men since she was a child because of her good looks. As a result, she has been living in seclusion in her family's mansion, using her specialty of blending to conduct her business.
However, Dorothy actually had a fiancée to whom she was engaged when she was 12 years old. And that man was Lucien Napier, the most twisted prince in the kingdom.
Lucien is also an extreme misogynist, and the two have never seen each other since their engagement.
Well, is there such a thing as a political marriage where you never see each other until the wedding ceremony?
