Emily: Sex & Sensibility (The Wilde Sisters, #1)

Emily Wilde has led a privileged life. Now, she's determined to succeed on her own. Marco Santini has worked his way up from poverty to great wealth. He's not interested in permanent relationships. She's not interested in being a man's pampered mistress. Becoming Marco's assistant seems to suit them both... until one night in Paris, when the passion smoldering between them turns to flame.
