London, England, 1814

Lady Anna Clifton will stop at nothing to find her missing brother--even if it means working alongside the dashingly handsome but sometimes infuriating Mr. Jennings, who just might steal her heart.

Lady Anna Clifton has arrived in London with a purpose known only to a few. Her soldier brother has been reported wounded and missing in France, and if he is dead, his title and their family's estate will go to a horrible distant cousin, and Lady Anna will be homeless. Desperate to find her brother alive, she contacts old family friends, the Bledsoes, who vow to help her in any way they can. However, Lord Bledsoe's efforts come up empty, except from the Duke of Aylesham, who offers his yacht to carry her to France when Anna decides she must look for her brother there herself.

James cannot board the Duke of Aylesham's yacht to take him to France fast enough. After his sister's rushed marriage to the duke himself, James wants nothing more than to enjoy a relaxing journey back to Paris before rejoining England's diplomatic war efforts against Napoleon. When he boards the ship, he cannot deny his instant attraction to the strikingly beautiful young woman who will be joining him across the sea. But when he receives only a cold reception from her, James dismisses her outright--until he learns the tragic reason she has set out on such a perilous journey. As infuriating as Lady Anna's brash behavior and indifference to him is, her search seems much too dangerous for a young lady of the ton to undertake alone, so James reluctantly offers to assist her in her quest.

Together, they embark on a search that will take them across the sea and through France to uncover the truth all while trying to reconcile their differences and the preconceived notions they have about each other. With every step, they come closer to solving the mystery surrounding Lady Anna's brother's disappearance--but each step also pushes their hearts closer together.
