About this book

Book 1 of The Duke's Sons series. As eldest son of the Duke of Langford, Nathaniel Gresham views his arranged marriage to Lady Violet Devere as another duty to discharge—a suitable match, but not an exciting one. When Violet begins transforming herself from a dowdy wallflower into a dazzling duchess-to-be, Nathaniel attempts to prove he can match her vivacity and daring. Having been oppressed by her family throughout her life, Violet anticipates the freedom that marriage will bring. However, she discovers a shameful family secret and faces a difficult decision: reveal it to Nathaniel and risk losing him, or conceal it and live with deception.
