For ten years, she's been invisible—just another cocktail waitress in Vegas's most exclusive underground poker den, serving drinks to men who think money makes them untouchable. But she's been watching, learning, memorizing every weakness and secret that slips out after the third scotch. When Adrian Cross, the untouchable billionaire who destroyed everything she once loved, walks into the Sapphire Room and doesn't recognize her, she realizes her moment has finally come. Now she has the perfect hand to play, and she's going all in on a game of revenge he'll never see coming. The only question is whether she'll destroy him before her own carefully constructed cover falls apart.
