I'm currently reading My Heart's Desire by Andrea Kane. This book is actually the 25th anniversary edition of the Regency Classic.
Lady Alexandria Cassel scorns the ton and all it stands for so she decides to leave England just before her first Season and visit her father who is working in Canada. Perhaps there Alex will be free to find her heart's desire. However, she continues her unconventional plan in a most unconventional manner. Taking no extra clothing, let alone a servant, Alex pens a hasty note to her mother, and stows aboard a Canadian bound ship. What she doesn't realize is that Captain Drake Barrett of said ship happens to be Lord Cairnham, one of the most elite members of the ton, who also holds that society in disdain.
As Duke keeps his identity quiet, Alex charms the rest of the men and slowly begins to melt Duke's icy heart. A happy ending however will be made more difficult by secrets, as well as Duke's treacherous younger brother, Alex's cold father, an upcoming war, and a ship caught in the crosshairs.
