As the daughter of the richest man in England, Allegra Morgan attracts a number of fortune hunters willing to overlook her flawed pedigree to gain her enormous wealth. Her most ardent suitor is the arrogant but impoverished Quinton Hunter, duke of Sedgwick, who has little to offer a prospective wife except his grand title. Allegra decides that if she must marry, she might as well be a duchess. So she agrees to the match with one condition - her husband must never ask for her love. Quinton is dazzled by his new wife's grace and fortitude, as well as the fierce desire that rages between them. Despite his best intentions, he finds himself falling in love with her. Then the terrors of the French Revolution hit close to home, and the two of them set off on a treacherous adventure that could cost them everything, including their final chance at happiness.
