Mistaken Identity : Regency House Party: Somerstone
(Book)

Can she truly love him if she thinks he is someone else? Jessica Standish is considered an upstart in the eyes of society because she is merely the daughter of a wealthy merchant. After a failed season, the devastating loss of her father and his fortune, her chances of a good match seem impossible. When her mother arranges for them to attend one of the biggest house parties of the summer, Jes dreads the idea of being seen as a fortune hunter. But then Lord Ian arrives. Even though she has only danced with him once, he has become the man of her dreams. As the connection between them grows, he seems so different from the man she thought she was. Conrad Pinkerton, the Marquess of Kendal despises the ton and all the scheming, the guises and the games that go with it. For years he has declined their invitations. Then his twin brother, Ian, calls in a favor and Conrad grudgingly assumes a guise of his own--pretending to be his brother at a house party. When he meets Miss Standish, he wants nothing more than to pursue her. But that would mean exposing his lies which would hurt both their reputations and threaten the relationship he didn't know he wanted. With family names and fortunes on the line, can Conrad and Jessica see past their schemes and guises to find a lasting love together?
