She always dreamed of marrying a Stuart brother. Just not the one who meets her at the altar.

When scandal sweeps through London's ballrooms, Lord Elijah Stuart's younger brother is caught in its web. Though his main duty is to England's spymaster, Elijah must forsake his work searching for the traitor to the Crown and instead focus on weddings and reputations. With both the family honor and his brother's future at stake, Elijah dutifully takes the ruined Miss Josephina Pennyworth for his very reluctant bride.

Furious at the circumstances leading her to be wed to the wrong Stuart brother, Josephina clashes immediately with her bossy new husband. She is every bit as invested in the search for the traitor as Lord Stuart and she is no shrinking violet when it comes to danger. While Josie discovers certain aspects of married life are quite pleasurable, she doesn't permit them to distract her from her mission. As she tests her husband's patience and the boundaries of her new life, the threat lurking in the shadows grows larger and places more lives in peril. Who among them will survive?
