Lady Violet Flowers has only one Season to find a husband. Raised in the Queen's household, Violet is elevated in rank, yet with no dowry, she will likely bring her mother disgrace, unable to find a good match, if any.
The widowed Marquess of Haverlane needs the perfect nanny for his beloved daughter, Jane. Fortunately for Haverlane, when the plump, but very pretty Lady Violet rescues Jane from almost drowning, the solution to his problem stands before him. After negotiating with her mother, Violet is ensconced at his country estate with Jane, and Haverlane and Violet communicate through correspondence, leading to an amiable affection.
Though unwilling to think of Violet as more than a nanny, a surprising Christmas kiss compels each to see the other in a new light. However, Parliamentary demands keep them a safe distance from temptation.
As the Season begins, an old flame emerges from Haverlane's past and attempts to rekindle that fire. Bereft, Violet accepts an offer for her hand. By the time Haverlane comes to his senses, he must do what Violet has dreaded most - bring scandal to her mother's house to try to win her back.
