Sultry jazz singer Caroline Spence has a penchant for smokier numbers-and, as it turns out, men of a similar temperament. So when the darkly dominant Marcus takes her on as his submissive, she surprises him by sharing his love of double cream, both in a bowl and on her body, as well as a passion for kink that could lose him his job. Still, it turns out Marcus isn't the only one who wants Caroline. The young, rich, and audacious Kyle could listen to her sing forever. Caroline soon finds out, however, that Kyle's obsession has a dangerous side. But with his charm and smoldering good looks, she finds it easy to let him push her a little too far. Two men. One siren. And a challenge that changes her life.
