Jonathon Effington, the Marquess of Helmsley must have been born under a lucky star-how else can he explain the fact that despite his frequently scandalous goings on, he hasn’t yet been found out for a cad by society. Instead, the ton thinks him just the very paragon of good behavior, and he is in the perfect position to find himself the same in a wife. But his friends suspect, rightly, that if he were to meet someone truly intriguing and fall for her in over his head, his prim and proper self would go right out the window and be replaced by a man consumed with infatuation. And they know just the woman to prove their point: the beautiful, untamable Fiona Fairchild. So when they scheme to put them in the same darkened room at the same time, sparks fly just as they thought. But then something completely unexpected happens: Fiona—yes, Fiona—proposes marriage! And, confused about her identity, Jonathon accepts! But when it turns out to be more than some madcap farce, both parties are astonished to find that despite their inauspicious beginnings, they are falling in love, and nothing can stop them both from getting completely carried away by the passion!
