Horatia Winwood is not a beautiful girl but she has a great heart. She sacrifices herself by marrying the Earl of Rule to save her family from financial ruin and most of all to help her eldest sister, deeply in love with a simple lieutenant, to escape a marriage without love. Moreover, to persuade Lord Rule, she promises not to interfere in his affairs. Can a marriage of convenience turn into a marriage of love? Sometimes it can. Only if you marry the fascinating Earl of Rule, though.
