Reluctant Duke [EPUB ebook] 

Lucan St. Claire refuses to take the cursed title of fifteenth Duke of Stourbridge—he wants nothing to do with his heritage, including a magnificent stately home in the English countryside. So when he’s forced to return to his family’s seat, he takes beautiful new personal assistant Lexie Hamilton with him for some much-needed distraction….Only Lucan has no idea that his temporary assistant isn’t quite who she seems…And by the time he finds out it will be too late!
