Always a Princess — Alice Gaines

Eve Stanhope masquerades as a foreign princess at ton parties, stealing jewels from the nobility she despises and returning to her London slum at the end of the night. She's carefully plotting revenge on her former employer -- a society cad who's ruined her reputation. Now it's her turn to ruin him. What she doesn't expect is to encounter the criminally handsome Orchid Thief on one of her heists...

Philip Rosemont, Viscount Wesley, is also in disguise. Bored and stifled by society, he steals jewels for fun and leaves orchids as his calling cards. He knows the woman he's cornered at the ball is no aristocrat, much less the Princess of Valdastock. But something tells him she's not exactly common, either. Now he must uncover her motives while he enjoys her illicit kisses. Can these two become partners in crime even as they give in to their mutual seduction?
