A Lady by Day — Alison DeLaine

Recovering from scandal, Josephine, Countess of Mareck, has secured a second chance at respectability. And she certainly will not risk it for Sir Noah Rutledge, who's returned to London from the Mediterranean to secure a new business venture. But when Noah confronts Josephine and puts her secrets at risk, he stirs a most unexpected desire. With the ton watching closely, she must be careful not to fall for an unsuitable man. Unless love proves stronger than Society.
